VPN access to site-toSite to servers of HO with remote site with overlapping network...
Hi all
I have an obligation to create a tunnel vpn site-to-site on ASA 5510 from a remote location to my HO, I have already other site to site tunnels are on the rise and running on the ASA. This is what my remote site got the network address that is part of a subnet used in HO(192.168.10.0/24). My requirement is only my need to access remote site couple of my servers in HO, who is in the subnet 192.168.200.0/24.
Veuileez help how can I achieve this... your advice at the beginning is very appreciated...
Thanks in advance

Hi Salem,
I think the installer at your end is a bit like this:
You want the remote location to access the subnet 192.168.200.0/24 behind the ASA HQ servers. In this case, you can NAT traffic from the remote site to a different subnet when you go to 192.168.200.0/24.
i.e. the 192.168.10.0/24 subnet resemble 192.168.51.0/24 when he goes to 192.168.200.0
This can be done by using political based natting:
permit access-list policy-nat ip 192.168.10.0 255.255.255.0 192.168.200.0 255.255.255.0
public static 192.168.51.0 (inside, outside) access-l policy-nat
In the encryption of the remote side access list, you will have:
cryptoacl ip 192.168.51.0 access list allow 255.255.255.0 192.168.200.0 255.255.255.0 (this is because the remote side will see 192.168.51.0/24 and not the 192.168.10.0/24)
Similarly on the end of HQ the accesslist crypto will be
XXXXX 192.168.200.0 ip access list allow 255.255.255.0 192.168.51.0 255.255.255.0
Please try this and let me know if it helps.
Thank you

Problem VPN site to Site with overlapping networks
We currently have a PIX 515E firewall as a headboard with many tunnels of site-to-site configured for her with the enpoints of PIX 506. Our internal LAN addressing scheme is 172.18.0.0 255.255.0.0. Addresses of local network in two of the remote networks with congigured VPN site-to-site are 172.18.107.0 255.255.255.224 and 172.18.107.32 255.255.255.0. Remote network access to all services on our internal network very well. We have 20 other network segments configured the same way. The 172.18.107.32.0 network needs to communicate with the 172.18.107.0 network for the services of file on the other remote PIX. Since the station PIX will not allow traffic to leave the same interface it came we thought with him we would just set up a tunnel from site to site between the two remote LAN. After the configuration of the site to another remote firewalls do not appear to try to establish tunnels when sending valuable traffic. I turned on debug for ISAKMP and nothing is either sent or received on a remote Firewall with regard to these tunnels. It's almost like since we already have a tunnel set to our 172.18.0.0 internal LAN that the remote PIX will not build specifically to 172.18.107.0 tunnel. I am able to ping each remote peer with each other and hear protection rules, but nothing has ever been established.
Is what we are trying to do possible? Sorry for the long post but the kind of a strange scenario. Thanks in advance for any help.
In what order are the numbers of seqence card crypto for configuring vpn on pix distance units? It could be that you are trying to install is a lot and will be checked later as head of pix. If this is the case, then yes the 172.18/16 road prevail the 172.18.107/24. Try to rebuild the entrance card crypto with a lower number so that traffic to 172.18.107/24 comes first.
I would like to know how it works.

Several tunnels to Datacenter VPN with overlapping networks
Hello guys,.
We are starting to host applications for customers who need trusts (maybe?) Windows and full access to a class C subnet in our IP data center.
My problem is most of our customers are small MOM and pop stores IPed to 192.168.1.x. I intend to install my own Cisco ASA in each of these sites and create a VPN to the data center to access the application. The last 2 sites I've done, I have re-IPed network to a mine plan. I start to run in many customers that we simply host the app for and I can't really make them Re - IP network if they do not want.
My question is what are my options here? I guess some kind of NAT, but I don't really know how it works. With a Windows trust communication must be 2 tracks. If we did not trust, I could see this work without problem with a simple NAT right? Firewall guy would you NAT on? The remote end or Data Center?
Any help and advice is appreciated.
I'm a complete network of Cisco, ASAs, catalysts, routers, etc...
Hi Billy,
Basically, for the overlap of networks, you will run natting on both sites for interesting traffic.
If you have networks that overlap, you can follow this link if you use Cisco ASA and this link for Cisco routers as a VPN endpoint devices.Kind regards

LAN-to-LAN IPsec VPN with overlapping networks problem
I am trying to connect to two networks operlapping via IPsec. I already have google and read
http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080b37d0b.shtml
Details:
Site_A use ASA 5510 with software version 8.0 (4) 32. Site_A use 10.100.0.0/24, 10.100.1.0/24 and 10.100.2.0/24 inside networks. 10.100.0.0/24 is directly connected to ASA (like vlan10), 10.100.1.0/24 and 10.100.2.0/24 are routed.
Site_B use Linux box and networks 10.100.1.0/24, 10.100.2.0/24, 10.100.3.0/24 and so on (mainly 10.100.x.0/24). I have not implemented this ASA, we took over this infrastructure without other documentation whatsoever.
According to the above link I should use double NAT. Site_B will see the Site_A as 10.26.0.0/22 networks, and Site_A see networks in Site_B as 10.25.0.0/24. Site_A is allowed access only 10.100.1.0/24 in the Site_B, and Site_B is allowed access to all the networks of the Site_A 10.100.x.0/24 - so / 22 10.26.0.0/22 mask. I would like, for example, ssh to host in the Site_B to host the Site_A using 10.26.1.222 as the destination ip address (and it should be translated in 10.100.1.222 on the side Site_A). I'm looking for something like ip nat type match-host in Cisco routers - I want to translate only a part of the network address leave the intact host Party. Anyway, following the steps from the link displayed above everything is ok until the command:
static (companyname, outside) 10.26.0.0 access list fake_nat_outbound
which translates into:
WARNING: address real conflict with existing static

TCP companyname:10.100.0.28/3389 to outside:x.x.x.178/2003 netmask 255.255.255.255
Those are redirects to port on Site_A used for mail, webmail, etc. What should I do to keep the redirects from the Internet to companyname vlan and at the same time to have work l2l ipsec tunnel linking networks that overlap?
Thank you in advance for any help or advice.

Are you sure that static-config does not make to the running configuration?
By applying this 'static big' you're essentially trying to redirect the ports, which have already been transmitted by the rules in your existing configuration. This explains the caveat: what you are trying to do has some overlap with existing static.
(Sorry for the use of the transmission of the word, but this behavior makes more sense if you look at it like this; although "port forwarding" is not Cisco-terminology.)
But... whenever I stumbled upon this question, the warning was exactly that: a WARNING, not an ERROR. And everything works as I want it to work: the specific static in my current config simply have priority over static grand.
If you would like to try to do the other opposite you would get an error (first static major, then try to apply more specific) and the config is not applied.
So could you tell me the config is really not accepted?

asa himself through site to site vpn access server
Hello
I have problem with access to the servers through site to site vpn to ASA that makes this vpn site-to-site and Clientless VPN enablerd.
Reason why I need it / what I do:
ASA 5510 enabled Clientless VPN and on this Portal allows users to access internal servers through bookmars URL. We use it when someone wouldn't access IPSec VPN or in an internet café. If this user connects to clientless vpn and click on the bookmark to access for example mail server. But there is problem, asa cannot access this server through VPN site-to-site.
Network:
Here's a quick design of my network.
I don't have server access to the problem in the VLAN 159 of VLAN 10, or 100. But I need to be able to access the server in Vlan 159 of ASA 5510, who owns the IP 192.168.1.4.
I have this subnet ASA owned by FRONT-NAT object in the same place that VLAN 10 to 100 are and vpn Site-to-Site profile.
What I makeover or how can I solve it?
Thank you
Clientless VPN when accessing internal servers, it will use the closest to the source of the connection interface and if you connect to via clientless SSL VPN ASA5510 and need access ASA5505 LAN via the site to site VPN, the interface closest to the ASA5510 to ASA5505 LAN is ASA5510 outside interface, therefore, the vpn of site-to-site crypto ACL must match on ASA5510 outside the ip address of the interface.
Here's what you need on each ASA:
ASA5510:
permit same-security-traffic intra-interface
ip 192.168.159.0 external interface allowed access list 255.255.255.0
ASA5505:
ip 192.168.159.0 access list allow 255.255.255.0 host
In addition, also need to add the same ACL for access-list of exemptions on ASA5505 NAT:
ip 192.168.159.0 access list allow 255.255.255.0 host
Hope that helps.

Win 7 64 bit: cannot access Web sites randomly
I had this problem for a long time, with several computers and various installations of windows.
After my computer has been for a few days, I'll suddenly find me unable to access all the web pages. Programs like MIRC, Skype and steam work perfectly, like online games. I just get a generic "unable to connect to the server" error when you try to access Web sites and I cannot ping all websites such as google.com (it instantly timeouts).
Do ipconfig/release, / flushdns and / renew fixes it for a few minutes before I lose the ability to access the Web sites again.
Disabling/renewal of the NIC does nothing and troubleshooting of windows doesn't find anything wrong.
The only semi-permanent solution I found is to restart my computer, but the problem will occur again in a few days.
Servers using openDNS makes no difference. Nor is switching between ethernet cable and wireless. This problem is not dependent on the browser. Reboot the router it corrects only for a few minutes until I became unable to use websites to access again.
Does anyone know what the cause of the problem and how to fix it permanently?
Hello.
I suggest you to configure the TCP/IP settings and check if it works:
http://support.Microsoft.com/kb/2779064/en-us
If the problem persists, I suggest you consult the website of the manufacturer of the laptop computer to download and install the latest network driver and check the results.
Please let us know if the problem still persists.

Remote RDP client VPN access on ASA 5510
Hello.
We have configured the VPN tunnel from site of offshore to the location of the customer using ASA5510 and access to RDP to the location of the customer. Also been configured remote VPN access in offshore location. But using the remote VPN client, we are able to get the RDP of officeshore location but not able to access to the location of the RDP client. Are there any additional changes required?
Thank you
Hi Salsrinivas,
so to summarize:
the VPN client connects to the ASA offshore
the VPN client can successfully RDP on a server at the offshore location
the VPN client cannot NOT RDP on a server at the location of the customer
offshore and the location of the customer are connected by a tunnel L2L
(and between the 2 sites RDP works very well)
is that correct?
Things to check:
-the vpn in the ACL crypto pool?
-you're exemption nat for traffic between the vpn pool and 'customer' LAN? is the exemption outside (vpn clients are coming from the outside)?
-you have "same-security-traffic permitted intra-interface" enabled (traffic will appear outside and go back outside)?
If you need help more could you put a config (sterilized) Please?

SRP526W to transmit or provide VPN access to clients
Hello
We have a SRP526W here, which replaced a cheap, simple router. Now, we would like to set up VPN access for outside clients again. So far, this was done by sending PPTP (TCP 1723 and GRE) for the Routing and Windows 2000 RAS server within the network.
According to this post SRP521W, and therefore I guess so the SRP526W, are not able to pass the GRE: https://supportforums.cisco.com/thread/2093204
Is it possible to provide external client VPN access with this router? Perhaps with L2TP (but then you should transmit ESP) or IPSec (ESP and AH as far as I know)?
If there is no solution, we need to replace this device again once with a cheap, simple, router that is able to convey the Grateful - as you can imagine, we would like to save this shame Cisco.
Kind regards
Dominik
Hello Dominik,
The SRP520 only supports IPSec site-to-site at this time.
Advancements are made, please check in the new year.

AnyConnect client cannot access external sites
I am installing AnyConnect VPN with no split tunneling. ASA 5505 v8.2. It seems that it should be really easy. I must be missing something.
I can get AnyConnect users to connect very well and they can access internal sites and on other sites in IPSec tunnel. But no access to internet.
Internal 10.1.1.x pool VPN is 10.1.1.251 - 253 (list of Temp for the test). I have published the following plotter:
packet-tracer input outside tcp 10.1.1.253 12345 69.147.125.65 80 detailed
The last reported point (where it fails) is:
Phase: 7
Type: WEBVPN-SVC
Subtype: in
Result: DROP
Config:
Additional Information:
Forward Flow based lookup yields rule:
in id=0xda7e9808, priority=70, domain=svc-ib-tunnel-flow, deny=false
hits=364, user_data=0xcb000, cs_id=0x0, reverse, flags=0x0, protocol=0
src ip=TempVPNPool3, mask=255.255.255.255, port=0
dst ip=0.0.0.0, mask=0.0.0.0, port=0, dscp=0x0
Which means by SVC-WEBVPN?
A relevant config:
No ACLs, filters or limitations of policy group on HQ customers.
Security-same permit intra-interface
Global 1 interface (outside)On advice, I've added: nat (outside) 1 10.1.1.0 255.255.255.0, then I can get no tunnel guests outside guests, but then no IPSec.
Kind of a weird, that with this, the tracer of package does not change. Continue to deny shows, but the site is accessible.
When you say tunnel IPsec sites... is that the tunnels IPsec Site to Site on the SAA?
The command:
NAT (outside) 1 10.1.1.0 255.255.255.0
It should allow the AnyConnect customer pool for PATed to Internet.
If you need clients AnyConnect to access the Internet and the access to remote IPsec tunnels as well, you can do it with policy NAT:
access-list anyconnect deny ip 10.1.1.0 255.255.255.0 x.x.x.x
access-list anyconnect deny ip 10.1.1.0 255.255.255.0 y.y.y.y
access-list allowed anyconnect ip 10.1.1.0 255.255.255.0 any
NAT (outside) 1 access list anyconnect
Global 1 interface (outside)
With the above configuration, you are bypassing NAT for AnyConnect customers when they want to access remote sites through the IPsec tunnels (assuming that x.x.x.x and y.y.y.y for remote networks through these tunnels).
And the rest of the AnyConnect (10.1.1.0/24) pool will be PATed to Internet.

VPN access to several local networks virtual asa8.3
you are looking for assistance. This one goes batty.
I have ASA 5510 8.3 running
It serves as a router, firewall and vpn.
the underlying network works fine.
When I connect via VPN, I can only access my reseau.41 and not on the reseau.42. When I try to do a ping.42 I get this error:
5 October 18, 2010 00:33:13 192.168.42.11 3389 rules asymmetrical NAT matched for flows forward and backward; Connection for tcp src Outside:192.168.43.200/2916 dst servers:192.168.42.11/3389 refused due to path failure reverse that of NAT
If I flip through these rules in order to config then I can acceder.42 through the vpn but pas.41
NAT (servers, all) static source any any destination static obj-vpnpool obj-vpnpool
NAT (iscsimgmt, any) static source any any destination static obj-vpnpool obj-vpnpoolI'm confused because it's all a new config and I used the wizard in asdm and couldn't access squat (perhaps he does not know how to manage the VLAN)?
the ASA may well ping of all networks.
devices on the network can ping each other fine
just via ipsec vpn, I can't access both networks.
thoughts?
Please configure a more specific NAT statements as follows:
object obj-iscsimgmt network
192.168.42.0 subnet 255.255.255.0NAT (servers, Outside) source static obj-servers obj-servers destination static obj-vpnpool obj-vpnpool
NAT (iscsimgmt, Outside) source static obj-iscsimgmt obj-iscsimgmt destination static obj-vpnpool obj-vpnpoolAnd pls Remove the following:
NAT (servers, all) static source any any destination static obj-vpnpool obj-vpnpool
NAT (iscsimgmt, any) static source any any destination static obj-vpnpool obj-vpnpoolThen "clear xlate" after the changes described above.
Hope that helps.

Access Web site external AnyConnect
Guys, I'm trying to allow AnyConnect VPN client to access external Web sites through the ASA (no split tunneling). In other words, I want users connected via VPN to gain access to the internal network, but also to be able to access external Web sites by having that first tunnel traffic to the ASA and then to the internet. I tried the suggestions mentioned in this thread, but not luck. Specifically, I tried adding this statement of nat:
NAT (outside) 1 192.168.30.0 255.255.255.0
as well as this one:
NAT (outside) 1 192.168.30.0 255.255.255.0 outside
By I had no statement "nat (outside). Unable to access outside sites in these three cases. I have no trouble to access within the network when connected. I issued the sysopt connection VPN-enabled control to ignore the interface of access for vpn users lists. Config is attached (washed). Any help would be greatly appreciated.
Change this line: nat (outside) 1 192.168.30.0 255.255.255.0 outside
To: nat (outside) 1 192.168.30.0 255.255.255.0
Global 1 interface (outside) will associate the NAT to the external interface.
Also make sure you have the traffic that is allowed between the hosts connected to the same interface with this command:
permit same-security-traffic intra-interface

ASA 5505 VPN Site to site with several networks
Hello
I have a Cisco ASA 5505 configuration problem and hope you can help me.
Our company created a second facility, which must be connected using VPN to our headquarters.
I used the ASDM "Wizard of Site to site VPN" to create a connection, which works very well with our main network.
Following structure:
Headquarters:
Cisco ASA 5505, firmware 9.1, ASDM version 7.1
Outside: Fixed IP
Inside: IP address of the interface is 192.168.0.1/24 (data network)
Now I have a second network 192.168.1.0/24 (VoIP network), PBX address is 192.168.1.10.
The two networks should be accessible through the VPN.
New installation:
Cisco ASA 5505, firmware 9.1, ASDM version 7.1
Outside: Fixed IP
Inside: IP address of the interface is 192.168.2.1/24
I have already created a connection until a PC of the new plant reaches the data network. For example, a ping from 192.168.2.100 to 192.168.0.100 is possible.
Now, I want to add some VoIP phones to the new facility, which can reach the PBX on 192.168.1.10.
In the link, I have already added the two networks as remote network:
object-group network Testgroup network-object 192.168.0.0 255.255.255.0 network-object 192.168.1.0 255.255.255.0 access-list outside_cryptomap extended permit ip object-group Testgroup object Remote-Network
My problem now is, I don't know what to define as 'Bridge' on my PBX.
I can't use 192.168.0.1 because it's a different subnet. Also, I can not put a second IP 192.168.1.1 to the interface of the ASA.
You have any ideas, how can I accomplish this, so that the two subnets are accessed through the VPN and all devices have a defined gateway?
Could a "Easy VPN Remote" in "Network Mode" you help me?
What is the difference between 'Site-to-site' and 'extended network '?
Kind regards
Daniel condition, look for the solution GmbH
You can optionally configure a new LAN VIRTUAL (VLAN PBX) on the SAA and connect this interface to the voice network.
If you do not have a spare on the ASA port, then Yes, you have a router to route traffic from the PBX to the ASA via the data network.

Ask about hub and spoke VPN between several sites
Hello
I currently have a 'hub' ASA 5505 that connects to 4 sites running 877 routers.
Since the network hub, I can connect to all the sites fine but what I would do is almost to compartmentalize the different VPN links in small groups.
The ASA 5505 hub mainly provides IP telephony via the VPN from a PBX allowing users at the other end of the VPN to make outgoing calls and receive incoming calls. However, a couple of the sites would be able to call them internally through the hub. It must obviously be allowed between their different networks of traffic.
Currently, when you try an internal call rings, but there is no audio data anyway. I guess that's due to restrictions of access list. I don't know yet if what I'm trying to achieve is possible as I'm a bit of a rookie, but any help would be appreciated. I have attached the hub and 2 rays below.
The ideal final result would be the interconnectivity between the two rays through the hub, it seems reading as its possible, but I do not understand my head around it! It would involve using different subnet to the hub masks?
Any help would be greatly appreciated!
Thank you
Jack

Unique password on SAA for VPN access
Hello
It is posibble create a unique password on SAA for VPN access?
I googled a bit and found a few solutions with unique servers from other suppliers.
I wonder if this is possible without additional hardware/software.
Hello
you will need to integrate the VPN with the RSA. they will give you once the configuration of the password tokenized soft or hard token.
Outside of RSA, there is no other choice I guess.
I hope this helps.
Kind regards
Anisha.
