i get the impression you're not familiar with how tht cisco vpn client works. by default it will shut all otehr network interfaces, isolating your pc from the network it is sitting on, and all ip traffic must go via the tunnel. this is a setting sent down from on high by the PIX or whatever you're other end is connected to. you can disable this, but it's something they need to permit at the other end, and is generally a bad idea to do so for security reasons. that said, the GPL vpnc client doesn't enforce these commands so you can keep those connections open that way, if you wanted to try that client.
