Well, you should have a G flag on the default route, but that doesn't mean you can't ping the remote box. You really shouldn't suffer with routing if it's a two-box network. I say go back to hardware, I can't see a software problem at all. > 22:00:01.427518 pc1.mydoman.com > pc2.mydomain.com icmp: echo request > 22:00:02.427518 pc1.mydoman.com > pc2.mydomain.com icmp: echo request > 22:00:03.427518 pc1.mydoman.com > pc2.mydomain.com icmp: echo request The echo requests go out, none come in. I bet the lights on pc2's hub point never blink. Or the nic, then. Run tcpdump on pc2 while pinging from pc1 to really check. > My Second issue: #2.
