Routing problem of inside inside via PIX
Hello
I use a Cisco PIX 506th Version 6.3 (4).
My inner interface is 192.168.5.1/24. The interface connects to a Cisco Catalyst 4503, the interface in question lies in the VLAN 20.
On the 4053, I recently created a new VLAN (30). This VLAN holds 192.168.6.0/24. On the 4503, I created an interface VLAN, which acts as a default gateway for the network 192.168.6.0/24, IP: 192.168.6.2. The IP address of the interface VLAN on 4503 belonging to VLAN 20 is 192.168.5.2.
My hosts in VLAN 30 have 192.168.6.2 default gateway - the Cisco 4503.
My hosts in VLAN 20 have default gateway 192.168.5.1 - the Cisco PIX.
I am trying to establish connectivity between the 2 networks. When I try to install between 192.168.5.10 (a random host) and 192.168.6.10 (another random host), I see that the PIX complains of not having a route to 192.168.5.10 192.168.6.10.
(Road No. 6-PIX-110001 to 192.168.6.10 of 192.168.5.10)
I have however to add a lane on the PIX that presents itself as such:
inside 192.168.6.0 255.255.255.0 192.168.5.2 1 ANOTHER static
So I will try to explain the PIX she can find 192.168.6.0/24 through 192.168.5.2.
With regard to the NAT'ing:
Global 1 interface (outside)
NAT (inside) 0 access list acl-sheep
NAT (inside) 1 access list acl-inside 0 0
I thought for a moment it could have something to do with NAT'ing, so I added this to the ACL acl-sheep:
allowed to access list acl sheep line 4 192.168.5.0 ip 255.255.255.0 192.168.5.0 255.255.255.0 (hitcnt = 0)
allowed to access list acl sheep line 4 192.168.5.0 ip 255.255.255.0 192.168.6.0 255.255.255.0 (hitcnt = 0)
allowed to access list acl sheep line 4 192.168.6.0 ip 255.255.255.0 192.168.5.0 255.255.255.0 (hitcnt = 0)
allowed to access list acl sheep line 4 192.168.6.0 ip 255.255.255.0 192.168.6.0 255.255.255.0 (hitcnt = 0)
Because I don't want PIX of NAT traffic.
After that, he always complains about not having a route.
Does anyone have an idea what I could always try to solve this problem?
With sincere friendships.
Kevin
Unfortunately, PIX does not route or redirect traffic on the interface, he received the package. Unlike a router, the PIX cannot route packets back through the same interface where the packet was originally received.

Another suggestion for you, is if there are only a handful of hosts on the NET 192.168.5.0/24 needed to arrive at the NET 192.168.6.0/24 you can add a static route on them for use as the next hop 4503 to access the 192.168.6.0/24.
Let me know if this helped.

VPN clients cannot access remote sites - PIX, routing problem?
I have a problem with routing to remote from our company websites when users connect via their VPN client remotely (i.e. for home workers)
Our headquarters contains a PIX 515E firewall. A number of remote sites to connect (via ADSL) to head office using IPSEC tunnels, ending the PIX.
Behind the PIX is a router 7206 with connections to the seat of LANs and connections to a number of ISDN connected remote sites. The default route on 7206 points to the PIX from traffic firewall which sits to ADSL connected remote sites through the PIX. Internal traffic for LAN and ISDN connected sites is done via the 7206.
Very good and works very well.
When a user connects remotely using their VPN client (connection is interrupted on the PIX) so that they get an IP address from the pool configured on the PIX and they can access resources located on local networks to the office with no problems.
However, the problem arises when a remote user wants access to a server located in one of the remote sites ADSL connected - it is impossible to access all these sites.
On the remote site routers, I configured the access lists to allow access from the pool of IP addresses used by the PIX. But it made no difference. I think that the problem may be the routes configured on the PIX itself, but I don't know what is necessary to solve this problem.
Does anyone have suggestions on what needs to be done to allow access to remote sites for users connected remotely via VPN?
(Note: I suggested a workaround, users can use a server on LAN headquarters as a "jump point" to connect to remote servers from there)
with pix v6, no traffic is allowed to redirect to the same interface.
for example, a remote user initiates an rdp session for one of the barns adsl. PIX decrypts the packet coming from the external interface and looks at the destination. because the destination is one of adsl sites, pix will have to return traffic to the external interface. Unfortunately, pix v6.x has a limitation that would force the pix to drop the packet.
with the v7, this restriction has been removed with the "same-security-traffic control intra-interface permits".

VPN inside a PIX (General Questions)
Hello
I'm trying to implement a scenario of communication between a customer inside a pix that talks to a server on the outside. The customer must have an ipsec inside connection. I have the following config and a few questions I´d be very happy to get an answer for...
Backup on the interface outside the security0 Server
Client safety within 100 interface
The client IP address is 200.200.212.194
backup server address is 200.200.202.201
I want to implement a VPN client connection to the inside interface, and therfore have implemented the following configuration.
external IP 200.200.202.200 255.255.255.0
IP address inside 200.200.212.193 255.255.255.192

vpngroup address private pool PRIVADAGROUP
PRIVADAGROUP vpngroup password *.
vpngroup split tunnel 100 PRIVADAGROUP
I have a few questions about this configuration maybe some kind soul able to respond.
1. the VPN clients receive an address (10.3.3.1) for example through the IKE negotiation. When I ping my server from the client with the active VPN tunnel I assume the real package that passes through the wire has 10.3.3.1 a source address and a destination of 200.200.212.193 (endpoint the VPN and inside interface). Within IPSEC, the package is my real ip with a source 200.200.212.194 address (address of the real client) and a destination address of 200.200.202.201 (address of the backup server that I am trying to ping). If all this makes sense and is correct could you confirm the following point.
2 when the PIX deencrypts the package and removes the IPSEC header I find myself with my IP packet of origin with a source 200.200.212.194 address (address of the real client) and a destination address of 200.200.202.201 (address of the backup server that I am trying to ping). I don't know if I need then the following configuration to allow the package to be transferred to the backup without NAT server:
access-list allowed sheep host ip 200.200.212.194 255.255.255.0 200.200.202.0 255.255.255.0
NAT (inside) 0 access-list sheep
I was previously using the following configuration and it seemed to work but the more I think the less sense it seems to do as I´d wait for the SENATE to run on the dencypted package. I must be missing something or confused, or both.
IP 10.3.3.0 allow Access-list sheep 255.255.255.0 200.200.202.0 255.255.255.0
NAT (inside) 0 access-list sheep
3. as a last and probably least I m pretty sure I don't have to line "isakmp key * address 0.0.0.0 netmask 0.0.0.0" when connecting with a VPN client software only. Somone can confirm that for me.
I'm actually trying to get this to work remotely with someone else doing the actual work and we don't speak the same language.
Any help to store my confused brain would be appreciated.
1. No, it's the other way around. The real package that passes through the wire has the address IP of the PC (200.200.212.194) as a source. Within the IPSec packet is allocated 10.3.3.1 as source IP address. When the PIX decrypts the packet, the outer header is removed, and the package has a source of 10.3.3.1 as it is sent to your server on the outside. The external server will respond to 10.3.3.1 so it must be routed to the PIX for her to work.
Think of this as the normal instance with the PC to the outside through the Internet. A package from of and sent to 10.3.3.1 would never do to the original PC. The encrypted IPSec packet always contains the VPN endpoints real IP source and destination addresses. The decrypted original deck contains allocated as source IP and the actual destination as destination (usually also a private address) computer.
2. This should make more sense now that you know the answer to 1.
3. you don't need that if you have a "vpngroup password xxxx" command. This command «isakmp key...» "If there is no specific vpngroup key, or someone connects with a different groupname.

Cisco SG300 / ASA 5505 intervlan routing problem
Dear all
I have a problem with the configuration correctly sg300 layer 3 behind the ASA 5505 switch (incl. license more security)
The configuration is the following:
CISCO SG300 is configured as a layer 3 switch
VLAN native 1: 192.168.1.254, default route ip address (inside interface ASA 192.168.1.1)
VLAN defined additional switch
VLAN 100 with 192.168.100.0/24, default gateway 192.168.100.254
VLAN 110 with 192.168.110.0/24, default gateway 192.168.110.254
VLAN 120 with 172.16.0.0/16, default gateway 172.16.10.254
Of the VLANS (100,110,120) different, I am able to connect to all devices on the other VIRTUAL local networks (with the exception of Native VLAN 1; is not the ping requests)
From the switch cli I can ping my firewall (192.168.1.1) and all the other gateways of VLANs and vlan (VLAN1, 100, 110, 120) devices
Asa cli I can only ping my switch (192.168.1.254) port, but no other devices in other VLAN
My question is this. What should I change or installation in the switch configuration or asa so that other VLANs to access the Internet through the ASA. I will not use the ASA as intervlan routing device, because the switch does this for me
I tried to change the asa int e0/1 in trunkport (uplink port switch also), to enable all the VLANS, but as soon as I do that, I can not ping 192.168.1.254 ASA cli more.
Any help is greatly appreciated
Concerning
Edwin
Hi Edwin, because the switch is layer 3, the only necessary behavior is to ensure that default gateways to the computer are set on the SVI interface connection to the switch to make sure that the switch is transfer traffic wished to the ASA.
The configuration between the ASA and the switch must stay true by dot1q, such as the vlan all other, unidentified native VLAN tagged.
Also, if I'm not wrong, on the SAA you must set the security level of the port to 100.

Hello forum, I have a question please answer if someone knows the answer...
Here is my scenario:
Central location Pix515 (192.168.0.0/24)
Location 1: (192.168.1.0/24)
Situation 2: (192.168.2.0/24)
Location 3: (192.168.3.0/24) local pool for vpn clients
192.168.0.0/24, 192.168.1.0/24 lan - LAN IPSEC
192.168.0.0/24 for 192.168.2.0/24 lan - lan IPSEC
192.168.0.0/24 to 192.168.3.0/24 ezvpn IPSEC
Question:
Is it posible to connect Location1 and Location2 via Pix, or Location1 and Location3?
On encryption ACLs on each location of traffic destined to another location is included for the encryption process.
for example, location1 acl:
Access 100 per 192.168.1.0 255.255.255.0 192.168.0.0 255.255.255.0
Access 100 per 192.168.1.0 255.255.255.0 192.168.2.0 255.255.255.0
Access 100 per 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0
other locations have a similar LCD-s
There is no problem to access locations 192.168.0.0/24, but traffic between sites does not work.
I think that pix encrypt packets outside ariving.
I know, it's possible on IOS with IPSEC over GRE tunnels with some routing, but PIX?
Republic of Korea
Hi Rok-
Allows traffic between VPN sites does not currently work with Pix OS 6.3.4 and earlier. Code pix 7.0, which will be published later this year, will enable traffic between the same interfaces of VPN security level. This will allow talked to talk communication. I have configured the week last with Pix 7.0 beta code, so I know this is a new feature and it will work.
IOS does not have this limitation with IPSec. The GRE is not required to IOS to make communication speaks to talk work, although it can be used.
I hope this helps you understand what is happening.
Please let us know this that followed by questions that you have.
Thank you!
Peter

Routing problem between the VPN Client and the router's Ethernet device
Hello
I have a Cisco 1721 in a test environment.
A net 172.16.0.0/19 simulates the Internet and a net 192.168.1.0/24 simulates the net, the VPN tunnel must go to (intranet).
The net 172.16.0.0 depends on the router 0 FastEthernet, Intranet (VPN) hangs on Ethernet 0.
The configuration was inspired form the sample Configuration
"Configuring the Client VPN Cisco 3.x for Windows to IOS using Local extended authentication"
and the output of the ConfigMaker configuration.
Authentication and logon works. Client receives an IP address from the pool. But there's a routing problem
side of routers. Ping client-side - do not work (the VPN client statistics that count encrypt them packets, but not to decrypt).
Ping the router works too, but decrypt and encrypt customer statistics in VPN packets count progressive
(customer has a correct route and return ICMP packets to the router).
The question now is:
How to route packets between the Tunnel and an Ethernet device (Ethernet 0)?
conf of the router is attached - hope that's not too...
Thanks & cordially

Thomas,
Can't wait to show something that might be there, but I don't see here. You do not have the card encryption applied to one of the interfaces, perhaps it was not copied. Assuming your description you do it, or should it be, applied to the fa0 and you are connected. Try how you ping? Since the router or a device located on E0? If you ping the router, you will need to do an extended ping of E0 to the ip address of the client has been assigned. If your just ping the router without the extension, you will get sales and decrypts that you declare on the client. Have you tried to ping from the client to interface E0? Your default route on the router is pointing to fa0? You have a next hop to affect? You have several NIC on the client pc? Turn off your other network cards to check that you don't have a problem with routing on the client if you have more than one.

Routing based on the source in PIX
Hello
I am trying to find a way to make a routing based on the PIX source to get the same functionality of the 'road-map' command in Cisco routers; is there an equivalent command for this PIX 7.x version? I remember that it was not available in previous versions and I couldn't discover version 7.x, also, but I wanted to confirm with you double.
Thanking in advance.
Kind regards
Haitham
Haitham,
Your interpretation is correct, Policy Based Routing is not supported on the Pix Firewall.
Also, don't you confused when you see the command option 'road-map' Pix 6.3 and higher. This command is applicable only when redistributing routes into OSPF.
6.3 Pix command reference:
http://www.Cisco.com/univercd/CC/TD/doc/product/iaabu/PIX/pix_sw/v_63/cmdref/Mr.htm#wp1017196
Command reference 7.2 pix
http://www.Cisco.com/univercd/CC/TD/doc/product/multisec/asa_sw/v_7_2/cmd_ref/qr_711.htm#wp1648744
Let me know if it helps.

Arial fonts in PDFs former problems! {Inside photos}
Hi all.
This is the problem as much as I can explain it!
I have pdf files that were created on a Mac origanally (I use Win 7) using the Arial Narrow font family. I read all of the posted questions
the policy of Arial Narrow problems, but none solved the problem. Here are the screenshots of what, in my view, could be the cause.
When I look at the properties in Acrobat for the PDF in question, here's what fonts appear.
The only font that correctly displays is true font type Arial Black. Type1 ArialNarrow views
as shown in the image below. Another thing to note: notice how ArialNarrow is one word?
Is this perhaps why Illustrator is having a problem with it? I tried to find it with no luck.
When opened in Illustrator CS2, it is what is displayed.
The fonts are in my repertoire of fonts in Windows and Illustrator. I even loaded the old 2.35
a version which is mentioned on the net.
The problem is that I have hunderds these documents some with more than 200 pages each. I messed up
with this for several days now and I am at a loss of what to do next.
Any help would be greatly appreciated!
Mark
Substitution of fonts in Illustrator by using Type > find font is not going to work.
If you look at the screenshots, you will see that the fonts are CID fonts with custom coding. The fonts on the computer of brands have probably ANSI encoding (for example standard Western character set) and character cards will not match. So you will not get text legible but just squares or other things (diamonds, points etc.)
Mark sent me a file to look at and here's what I wrote in direct e-mail to him.
The problem is that the PDF was made directly from InDesign, which converts the fonts fonts CID (normally used for Asian fonts such as Chinese, Japanese and Korean) and, in so doing, he created a table of characters (encoding) that is not compatible with our ordinary fonts that use the character of Western (ANSI) encoding. Which explains why the replacement police incorporated by one on your system does not work.
There is some info on the Adobe website at the following links:
http://kb2.Adobe.com/CPS/329/329611.html
http://InDesignSecrets.com/CID-identity-h-fonts-are-back.php
http://forums.Adobe.com/thread/324995Also, the problem of the CID character exists in Acrobat 7 and 8, but got solved in Acrobat 9.
The only thing that has worked to get a PDF with readable and editable text was to use an OCR program (Abby FineReader in my case, but Omnipage can do the same thing) to process the PDF and embedded fonts are basically OCR'ed use system fonts and then resave PDFs had basically the same effect that replace the embedded fonts to system fonts. After that opening the PDF file in Illustrator has normal text and the file can be changed. Although Serif DrawPlus does a better job by opening the PDF file in editable format.
In this case, the road of the OCR is an option because the PDF contained a table. If this had been a drawing that the OCR option can be less useful depending on how the OCR software manage the drawing part, unless you get the text on the PDF and reinsert it into the drawing would be sufficient.
The above information may be of some use to those who are faced with the same problem.

WRT600N advanced routing problems / use as Access Point and switch
Firmware 1.01.36 build 4 The WRT600N is connected to an existing LAN and is really only used as a Wireless N access point. There is nothing plugged into the WAN port; only the LAN port. I have NAT disabled. All traffic from a client connected to the WRT600N wireless going very well for the gateway and the Internet router. The customer experience is very good. However, there are a few minor issues as follows.
1] Setup > Advanced Routing tab has only the following options; to do this, * not * have a picker 'Mode '. NAT, static routing and dynamic routing (RIP). IS this NORMAL, OR should HAVE a MODE (e.g. switch) AS REFERRED to IN THE HELP FILES?
[2] even if a connection wireless or wired to the WRT600N works very well, the WRT600N himself is unable to connect to the internet. It cannot connect to NTP to set the time and I can't ping past the gateway router using the ping of the WRT600N diagnostic utility. I ping the gateway 192.168.1.4 port inside, but I can't use the diagnostic the WRT600N ping ping utility something beyond this gateway port. The routing of the WRT600N table is below. THE GATEWAY SHOULD NOT BE 192/168.1.4? HOWEVER THE WRT600N DON'T ME LETS NOT CHANGE IT.
Destination LAN IP Subnet Mask gateway interface
192.168.1.0 255.255.255.0 192.168.1.71 LAN & Wireless
127.0.0.0 255.0.0.0 * LAN & Wireless
Topic 1. Linksys, used to have a mode option to switch between the modes 'Bridge' and 'router '. The latest routers call it now better NAT power. Gateway mode means THAT NAT is enabled. Router mode means THAT NAT is disabled. The help files are probably a little bit over. But the option is still the same.
Re 2. It's normal if you use it as only access point (i.e. do not use the WAN port). The router always takes into account that the internet connection via the WAN port, i.e. it will always use the default gateway on the WAN port. If nothing is connected to the WAN port on the router itself has no default gateway and therefore has no access to the internet. Generally, you are not able to establish the default route in either advanced routing page. It is a known limit of these routers if you do not use as a router.

PowerConnect 6248 routing problem

I have a very frustrating problem with routing using a PowerConnect 6248 switch.
Network configuration is the following:

172.16.0.254/24
VLAN4
192.168.0.254/24
PC on each VLAN using the switch VLAN interface IP (x.x.x.254) as the gateways.
Switch has configured default route to 192.168.0.248 which is a router with excess of 100 subnets frame relay cloud. 192.168.0.248 has routes suitable for all remote subnets via a serial interface, a static route to VLAN 3 (172.16.0.0/24) traffic through 192.168.0.254 and one way by default via a PIX 515 (192.168.0.253). Router and PIX is connected to access VIRTUAL 4 LAN ports. The PIX has a route to VLAN 3 traffic through 192.168.0.254.
The problem is that VIRTUAL 3 all hosts on the local network cannot access the Internet. They can ping the gateways in the order - 172.16.0.254, 192.168.0.248 and 192.168.0.253. I have disabled IP forwarding on the router and the switch with no effect.
I built this configuration in Cisco Packet Tracer 5.0 (it works) and we are running exactly the same IP configuration with a Nortel switch instead of the Dell 6248 (this also works).
Absoloutely perplexed to find out what I'm missing! I also noticed that if I perform a traceback while in the CLI on the router using a source IP address of the interface VLAN that it blocks the interface on the switch.
I would be very grateful to anyone who can punch me in the right direction.
I've included the config switch below.

Cisco SA540 - classic routing problem - 0.0.0.0 in static road
Hello, I am a bit newbie with routing device,
I had several public IP address
I got a Cisco Pix 501and want to replace it with a Cisco SA540
My Wan IP on Pix 501 is 195.68.x.z
My Lan IP on Pix 501 is 62.23.a.b (and 62.23.a.c,...)My rules Pix 501 translation is: inside the interface. inside: everything: 0.0.0.0. Apart from the interface. same as orginal
My Pix 501 static route: outside | IP address 0.0.0.0. Mask 0.0.0.0. Gateway IP 195.168.x.y | Metric 1So when a computer with 62.23.a.X want access to the internet the static route he say to throuw the 195.168.x.y of the IP Address of the gateway (as I undestand)
I replicate this config on my SA540
Also, through the Web user interface, I configure the Wan and Lan IP
and then in the routing menu, I check "Classic routing" so I go to the static Menu to add the same route as in my Pix 501, but I can't put 0.0.0.0 in iP address or IP subnet mask.Can someone help me?
Thank you very much.
Hello
I hope this finds you doing well. Just thought I would add a few things here...
You have probably seen this, but... Here is the link to the page SA500:
https://www.myciscocommunity.com/docs/doc-10526
Yes, when you configure the device as a router, you need to configure routing. Try to remove the routes and the readd.
In addition, a little off topic, but if you want to stay with an ASA5505, there used to be a tool that would turn your PIX configus ASA. I don't remember where this link is now... but it used to fairly simple transition.
After you have configured the routing, since your internal machine, have you tried a trace route? On what device the traceroute fails?
In case you wish to speak to a support representative, here is the link to find the correct number:

Problems with VPN between Cisco PIX 6.3.3 and VPN 3000 Concentrator
Hi guys,.
I hope this is the right place and that someone has encountered this before I don't have much hair left to offset - I'm trying to set up a tunnel between our Pix 6.3.3 performer and a customer using a VPN3000.
The customer wants us to be able to do checkups on a device without allowing anything to of our range of addresses network side private, just one public IP address. We currently run a VPN to our recovery site to allow off-site replication, but the ACL on the other end of this VPN * does * allow the configuration that we had for our private network side, so traffic was not useful at that. Here is a screenshot of what I tried:
ethernet0 nameif outside security0

My hope is that anything on the 192.168.1.0/24 would be able to get out of the external interface as our only our public IP addresses (i.e. X.Y.Z.230), but the traffic they see on the other end is coming from the 192.168.1.0 network. I tried to remove the line inside_outbound_nat0_acl think she would use then the world but still do not have a bit of luck and the only difference I see on Kiwi Syslogd is that the src_proxy changes to 0.0.0.0 where is shows the IP address of my private side (for the purposes of the config above let's call it 192.168.1.135).
THANKS MUCH FOR ANY HELP!
-Mario
Hello
For example, you can NAT your internal via the tunnel network traffic when you go to this customer.
In this way, they will see your unique internal network as an IP address.
Let's say, rather than them seeing your internal 192.168.1.0/24, eelle will see your traffic like X.Y.Z.227
Is this what you need?

IPSec site to site VPN cisco VPN client routing problem and
Hello
I'm really stuck with the configuration of ipsec site to site vpn (hub to spoke, multiple rays) with cisco vpn remote client access to this vpn.
The problem is with remote access - cisco vpn client access - I can communicate with hub lan - but I need also communication of all lans speaks of the cisco vpn client.
There are on the shelves, there is no material used cisco - routers DLINK.
Someone told me that it is possible to use NAT to translate remote access IP-lan-HUB customers and thus allow communication - but I'm unable to set up and operate.
Can someone help me please?
Thank you
Peter

How the DLINK has been configured for traffic between the site to site VPN subnets? You are able to add multiple remote subnets on DLINK? If you can, then you must add the pool of Client VPN subnet.
Alternatively, if you cannot add multiple subnet on DLINK router, you can change the pool of Client VPN 192.168.6.0/24, and on the crypto ACL between the site to site VPN, you must edit the 180 existing ACL
DE:
access-list 180 allow ip 192.168.7.0 0.0.0.255 192.168.1.0 0.0.0.255

TO:
access-list 180 allow ip 192.168.6.0 0.0.1.255 192.168.1.0 0.0.0.255
Also change the ACL 190 split tunnel:
DE:
access-list 190 allow ip 192.168.7.0 0.0.0.255 192.168.200.0 0.0.0.255
access-list 190 allow ip 192.168.1.0 0.0.0.255 192.168.200.0 0.0.0.255
TO:
access-list 190 allow ip 192.168.7.0 0.0.0.255 192.168.6.0 0.0.0.255
access-list 190 allow ip 192.168.1.0 0.0.0.255 192.168.6.0 0.0.0.255
Finally, replace the remote subnet 192.168.7.0/255.255.255.0 192.168.6.0/255.255.254.0 DLINK.
Hope that helps.
