Hello, I have a system running Linux-Mandrake 6.5 with two ethernet cards configured. One takes the ip packets from my cable modem provider (eth0) and the other forwards the packets to my internal network(eth1). I use ipchains for the forwarding. For some reason, I have to shut down eth1 before I can start my Xwindows session. Then I have to bring it back up. Until I do this the rest of my internal network cannot see the DNS servers provided by my cable modem service but I can see the gateway. Has anyone seen this before, or know what might be happening. TIA , Nathan
