Aaron, Here's a datapoint where it works correctly. I have four systems in a 192.168.1.0 network behind a gateway router providing NAT and reserved DHCP services: # ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:03:47:90:C2:D7 inet addr:192.168.1.4 Bcast:192.168.1.255 Mask:255.255.255.0 (blah blah blah...) Are you using static addressing? If not, what does your DHCP server config look like? --Doc Savage Fairview Heights, IL
