Problem of routing in PIX 515E

Hi all

I have a problem here with the routing routing in PIX515E version 6.35. I have a few Client PC located in the DMZ of the PIX515E interface, they connect to the PIX using Cisco VPN Client (IPSEC VPN), once these computers can be routed to access servers (static route) located behind internal PIX interfaces. I have a few servers remotely with access to the Internet, the gateway router to connect remotely to PIX Outside (Internet) Interface using IPSEC VPN and then routed inside the Interface (static route).

After establishing a VPN IPSEC computers Client behind the DMZ interfaces can access servers located behind the internal Interface of a PIX. So do the remote servers. However, the Client computers cannot access remote servers.

I was wondering if there are any restrictions for the delivery in PIX?

Thanks for the reply.

Hello

Thanks for posting, sorry for the late reply, been a little busy!

I'm not to clear on how you route your networks, I personally try to be more specific in what is routed where when the static use of the routes that the large 16s prefixes.

you have vpn l2l to allow remote access within your acl as crypto 172.16.0.199/32 to your server:
Access ip 172.16.0.0 Remote_Server list allow 255.255.0.0 host 172.16.0.199

and also you have cleared nat rule:
NAT (inside) 0 access-list sheep

for the resources of DMZ RA VPN 172.16.45.129 for server access through this VPN L2L wallpaper external interface, you need to activate in your acl L2L Tunnel end as well as for the valuable traffic.

The end has access-list for the tunnel L2L is allowing the network of Client VPN ID?

I would also like to add to your rule exempt Ant configuration on interface dmz as you do with inside interface

NAT 0 access-list sheep (dmz)

Let us know how it works, I'll be back on your config and after some more later.

  • PIX 515E configuration problems

    I have a UR PIX 515 (6.3.2 os) that works really well, so I copy the configuration on my new PIX 515E-R (os 6.3.2). The PIX 2 have exactly the same configuration. But when I use the PIX 515E-R, I have some problems with the PIX 515E r only

    -I can't access the Internet, but I can ping the router Internet of my PIX 515E. The problem, in my view, must be with the Internet router, not on my external interface.

    -J' have a similar problem with my DMZ. I can ping to the DMZ, a frame relay router interface, but I can't pass this router.

    Is it possible that PIX 515E-R is not compatible with the router? and not the PIX 515 HEART?

    Thanks for your replies.

    Hello

    Just a thought, try clearing the PRA of table on the router and see what happens. Let me know if it helps.

  • IPSEC VPN between Pix 515E and 1841 router

    Hi all

    BACKGROUND

    We have implemented a site to site VPN IPSEC between a Pix 515E 8.0 operation (4) and an 1841 using static IP addresses at both ends. We used CCP on the router and the ASDM the pix to build initial tunnels. Now the site with the router is evolving into a dynamic IP address from the ISP so we have implemented dynamic DNS to update dynamic IP address.

    PROBLEM

    The problem is that ASDM will not allow us to set a domain as the address of peers, it will not accept an IP address. We believe that the solution will be to remove the static Crypto map and replace it with a dynamic Crypto map on the side of Pix. Our questions are simply; is this the best solution? can change us the original static list or is it better to delete and make a new dynamic encryption card? Y at - it a shortcut to change the config command-line? This is a real network, so just check it out before make us any changes on the live kit.

    Any help much appreciated.

    You don't have to change anything when the peer-address changes. The dynamic crypto map aims to take dynamic peer connections. The only thing to remember, is that only the dynamic peer can initiate the connection. And you reduce your security if you use Pre-Shared key that now you can use a generic-PSK character.

    As I remember, the PIX / ASA does not support the dynamic use of FQDNs for peer-resolution. This feature is supported in IOS.

    For a feature, it would be preferable to static IP addresses on both sides.

    If you see the MM_WAIT_MSG2, which means that her counterpart (the other side) does not answer and this side where you can see the status MM_WAIT_MSG2 sent the first message IKE, however, did not hear of the peer.

    You can check if UDP/500 is stuck on the way between the 2 sites.

    Try running traffic on the other side and see if you also get the same status of MM_WAIT_MSG2. If you do, that confirms 100% 500/UDP is blocked on the way between the 2 sites.

    Try to add the "isakmp nat-traversal" command to your PIX. I suspect what happens is that Remote LAN users is translated to a single IP address as they pass through the DSL connection. I also assume that the machine doing the translation has a capacity of IPSec passthrough. Linksys routers would be a good example of this type of NAT device that allows IPSec pull-out.

    If that's the case, that a single VPN connection will be able to operate both. The above command will turn PIX detect clients that are located behind a NAT device, and then try to configure the VPN sessions in UDP packets and so to work around the limitation of NAT and IPSec passthrough device.

  • PIX 515E v7 VPN config help

    Hello

    I have a PIX 515E current of execution to 7.

    Is it possible to use VPN with only 1 static IP address from the ISP (no gateway or the ip address of the ISP router is provided).

    I can set up routing on the ADSL modem, but then the PIX does not have a valid Internet IP address?

    I think that v7 does not support PPPOE? so I can't set the mode on the bridged adsl modem?

    Is there a way to fix this?

    Any help appreciated gratefully.

    apply the commands below:

    ISAKMP identity address

    ISAKMP nat-traversal 20

    If the problem persists, then please post the entire config with ip hidden public.

  • Cisco VPN Client Authentication - PIX 515E-UR

    Hi all

    I need your expert help on the following issues I have:

    1. I would like to create more than 1 client VPN on my PIX-515E groups. This is so that I can give a different part of the internal network access to different type of VPN connection. For example, I want a group to have no XAUTH, while the other group must use RADIUS XAUTH. Is it possible for me to do this? I see the PIX automatically enable RADIUS on both groups of VPN clients.

    2. the RADIUS server is a Microsoft ISA with IAS server and it is located on the PIX inside interface. The VPN endpoint is external interface of the PIX. Is there a problem with this Setup? Do I need to have the RADIUS server that is located on the external interface?

    3 can. what command I use to debug RADIUS authentication?

    Thanks in advance for your help.

    Hi vincent,.

    (1) you can use the vpngroup *-authentication server ipaddress to specify the IP address of the Radius Server on a particular group... If you do not specify this, the authentication of the user is made locally... also check for vpngroup * order of user authentication

    (2) there should be no problem with the installation of your... should work fine... If the RADIUS is outdoors, it is subject to many attacks... so have it inside...

    (3) use the "RADIUS session debug" or "debug aaa authentication..."

    I hope this helps... all the best... the rate of responses if found useful

    This PIX has a failover license only (FO).

    Problem is that we cannot ping inner harbor, if we do not switch light, but this is a unique machine. Here's another message once we turn on the switch:

    PIX-515E # config t

    WARNING *.

    Configuration of replication is NOT performed the unit from standby to Active unit.

    Configurations are no longer synchronized.

    PIX-515e (config) #.

    Please help solve this problem. I wonder if we buy the wrong license? Thank you very much.

    you have in your possession a PIX failover. That's why says in the "sh run".

    This device is intended to be used only as a failover for a live device. It will work as a live PIX, but behave badly. It is cheaper than a PIX with an unrestricted license, as it is not intended to be used as a standalone device. Check with the one that you bought to get the situation sorted.

    Good luck

  • ASDM 5.02 on PIX-515E

    When I use ASDM to administer my PIX-515E (v7.0), I get messages from 2 following error if I update the screen after being inactive in the session for about 2-3 minutes about:

    Error message 1

    ASDM is temporarily unable to communicate with the firewall.

    Error message 2

    ASDM is unable to reach the PIX. Please check the configuration and your connection and try again by clicking the Refresh button.

    These messages were recently and I don't know why. Is there an ASDM idle session time-out setting? I could not found.

    Thank you

    Hello

    What version of Java are you using. If you have Java 1.6, can you go back to 1.5 and see if the problem goes away.

    Also, here is the URL indicating the operating system for client PC and browser requirements

  • PIX 515e Install

    I am installing a PIX 515e with an ADSL router. I have all the IP addresses for the router etc. I'm trying to connect to a network on the interface internal of the PIX. (Please bare with me as I am new on the firewall!)

    I ping the network firewall, but I can not access to the internet. The initial configuration for the PIX documentation implies that by default, it has access form the firewall but no! I'm obviously missing something here, i.e. of Thompson the network to route requests through the firewall interent! ???

    Sorry to be so simplistic but I'm learning all the time!

    Thanks for any help.

    After you enter the acl to allow ping, can you ping now?

    Watch newspaper reveal something?

    For DNS and testing, create a static on the PIX for your DNS server. For example "x.x.x.x (indoor, outdoor) static 192.168.0.x netmask 255.255.255.255" where x.x.x.x is a public IP address and 192.168.0.x is your dns server. Then let the outside to your DNS server dns - "access-list 101 permit host udp/tcp host x.x.x.x eq 53 z.z.z.z ' where z.z.z.z is a public dns server (or use one for testing) and x.x.x.x IP NAT'ed to your dns server. See what is happening, look in your journal.

    What version of PIX you run.

    Let know use.

    Hi hiren,.

    See the answers below:

    #Router inside the IP - 172.16.29.1 (inside property intellectual as it is very critical that cannot be changed)

    When you upgrade the PIX router inbetween and your switch, you must put the PIX inside IP like 172.16.29.1 and change the router within the subnet to someother pool. Do the PAT on the PIX, rather than the router.

    Outdoor #Router ip - what ip should I use? (I tried with 1.1.1.1 255.255.255.0)

    Router outside the property intellectual property will be that given by the ISP... The ISP would have given a public IP address for the WAN link. This cannot be changed.

    #PIX outside intellectual property - what ip should I use? (My ISP IP?-j' tried with 208.144.230.197 which is currently outside of my router)

    PIX outside IP must be comprehensive. ISP would have given you a LAN subnet. Use it. In this case, inside the interface of the router has an IP address from that subnet even...

    #PIX within the intellectual property - what ip should I use? (I tried with 1.1.1.2 255.255.255.0)

    PIX inside must be 172.16.29.1, which will be the default gateway for all PCs. If you change this subnet, then the PC should have an IP address on the same subnet that has decided.

    Connection ISP #My is directly from the ISP GW to an ethernet cat 5 on my router VLAN

    didn't get it... is that on the internet router or switch?

    #I would allow www, FTP, web-based like Yahoomail... etc... & Messenger services

    If all these must be permitted from inside to outside, you have not open anything... by default, all traffic to the inside outside is allowed (except if you put a list of access denied)...

  • PIX 515E failover recover

    I have two PIX 515E firewall v7.01 configured in a failover scenario.

    The two units were operating without problem. Primary worked very well and the configuration changes have been transferred to secondary school.

    By TAC support, the only thing needed to test the failover was to issue a command to 'reload' in the primary and the secondary, take on main. Then, "active failover" question on the once rebooted device it was up in the secondary role.

    Failover to the secondary unit worked without problem, it is a smooth transition to the secondary unit.

    The problem came in that the original primary unit is stuck in a loop when you try to reload with what looks like now configuration errors. It will not properly start upward.

    Is not a valid procedure to test the failover?

    It seems that in the real world, this could actually happen that failover should work?

    Among what is shown:

    Config ERROR: invalid journal / level keyword specified; level must be emergencies (0) - debugging (7)

    Config error - acl_in list extended access permit tcp any newspaper SMTP host 208.13.32.36 eq

    Out of config line 359, "access-list acl_in exten...". »

    Config sync error: Suite not command could be executed in standby mode

    Platform

    acl_in list access permit tcp any host 208.13.32.36 eq smtp log inactive

    Use BREAK or ESC to interrupt boot.ridge/vlan/modify flash): m

    e inactivea VLAN

    REPLICATION OF CONFIGURATION OF ACTIVE TOWARDS THE RESCUE UNIT IS INCOMPLETE,

    Reading of 115200 bytes of the image of the flash.

    TO AVOID THE EVE OF TAKING OVER AS ACTIVE WITH A PARTIAL CONFIGURATION UNIT, THE EMERGENCY UNIT WILL NOW RESTART *.

    You're not going to like this answer.

    It seems that commands typed in and abstract by cisco in the configuration are not valid when copied/pasted in or when the firewall is rebooted or receives an active firewall configuration.

    I don't know exactly what you did, but here's what I did to reproduce your problem:

    I typed in the command:

    acl_in list access permit tcp any host 208.13.32.36 eq smtp interval 300 inactive information newspaper

    Given that "interval 300 ft newspaper is the default, it is actually saved in the running-config like:"

    acl_in list access permit tcp any host 208.13.32.36 eq smtp log inactive

    It's * not * a command invalid (the word "journal" following address must be a logging level), if you try to kick it. When you restarted the firewall, he tried to shoot the active configuration of the device (because it is now pending), received this line and since he can't run it (because it is not a valid command), it keeps restarting itself so that it cannot take over and be the active firewall.

    Best way to do is to hold this line (and other lines like him) outside the firewall active now - the line is marked "inactive" in any case, this should not affect you. The other way would be to change that line to something by default (the recording level change may be easier). In this way when the primary/secondary itself restarts again, the order received will have a valid log level (or if you take the lines out, they will not be a problem) and will allow the rest of the configuration process.

    You can also report to cisco as a bug, if they are not combing these forums already.
