Cisco Pix 501 VPN - Wrong Gateway Help

[M4cc45]

Hi All

I have a Cisco Pix 501 which I have configured to allow VPN connections via the Cisco VPN Client.

Everything works fine - apart from the fact that the wrong gateway is displayed meaning that to do anything I have to Remote Desktop into the PC. Ideally I would like to have the ability to use anything connected via the VPN link to be part of the network thus allowing it to connect to exchange, etc.

I can't seem to find anywhere via the PDM to change the gateway it goes through.

Can anyone help?

Thanks!

I'm not quit sure what you mean by "displaying wrong gateway", if everything is ok then that should include the route as well, when you say RDP to the machine are you doing this via the VPN tunnel or over the net directly to the server.

can you please paste you VPN configuration here, obviously remove any sensitive details

Hi,

As you will probably guess with my next response I am not too familiar with the Cisco devices - thus I don't know how to get it to print out the config.

What I mean is that when I connect to the VPN via Cisco VPN the IP is like this:

IP: 10.10.0.70 (Correct)
Subnet: 255.255.255.0 (Correct)
Gateway: 10.10.0.1 (Incorrec this points to a server - should be 10.10.0.253)

DNS: 10.10.0.3 (Correct)

If you tell me the command to get the config (though I'll google it now) I'll gladly copy it here.

Ignore the above. Found the command it's obvious really.. you will notice below lots of IP's with 192.168 (this is the old range) which need to be changed/removed. I have put (wrong IP) next to them and also theres some users on there for the VPN part which I can't see in the PDM which need to be removed.

The first thing I would change is the IP pool for the VPN users

no ip local pool VPN 10.10.0.75-10.10.0.100
ip local pool VPN 192.268.250.1-192.168.250.254

access-list nonat permit ip 10.10.0.0 255.255.255.0 192.268.250.0 255.255.255.0

nat (inside) 0 access-list nonat

You might also want to enable split-tunnel so you can have access to both the net and your local network whilst you have the tunnel up

Hope that helps
