This is a bit of bizarre problem, and i'm not convinced the problem lies with my linux machine.....

I have a fedora core 2 server that has been installed in another company. In order to get remote access i am using a vpn tunnel from my work to their cisco pix router/firewall/etc. The linux server in on a network connected to one port of this router: with an ip on network, 10.110.110.x , and the pix as the default gateway.

When i log in to the vpn, i am given an address of 192.168.11.1. If i send packets (eg ping/ssh) to 10.110.110.x then they get sent through the vpn, but no packets come back. If i do traceroute 192.168.11.1 from the server, it cannot get packets through to my vpn connection.

Packets are definitely going out through the vpn connection. The guy setting up the firewall says that the linux box probably doesnt know what to do with packets that it needs to send to 192.168.11.1.

I think it will just use the default gateway. I've done a few experiments with a couple of linux machines and traceing route to 192.168.11.1 or 10.x when they are on totally different networks and they seem to send out packets, which eventually get returned by a router says get lost!

So can anyone give me any clues to this? I think the firewall/router/vpn endpoint isnt set up properly, and is probably blocking/not routing packets properly.

Any ideas?
