That's not good. Also, I don't think that any standard say to do that. Enrico

Debian doesn't like it though. They are configured to use DHCP? Are you sure that they aren't using another gateway? > Traceroute to 146.243.124.1 from 146.243.56.254 has one hop.... > > 1) 146.243.124.1 (146.243.124.1) 1.903 ms * 1.755ms > > Shawn What OS? Can you post your routing table? And, of course, netmask and IP address? Enrico

Please go to a working Windows computer and post what route print shows (activate cmd.exe and write the command). Also go to a working Mac and post what netstat -nr shows (activate Terminal and write the command). -- Tauno Voipio
