When you say "I have 2 if" and list the addresses eth0=192.168.200.11 and eth1=192.168.2.189, this must be another host (C?) that you are intending to use as an internal router to the internet router at 192.168.200.17. Right? I see two problems with the information you supplied. 1) Delete the following lines from your route table--they are unnecessary, and might actually be your main problem: 192.168.2.0 192.168.2.189 255.255.255.0 UG 0 0 0 eth1 192.168.200.0 192.168.200.11 255.255.255.0 UG 0 0 0 eth0 2) The (apparently default) gateway of 192.168.200.11 for host B means that B must send to router C, which then must resend _on the same LAN_ to 192.168.200.17. This makes C a one-armed router, unnecessarily routing packets that could go directly to the correct router. The default gateway for host B should be 192.168.200.17. A more consistent configuration for hosts A and B, would be something like this: Host A (192.168.2.100): 192.168.200.0 gw 192.168.2.189 (network route through host C) 0.0.0.0 gw 192.168.200.17 (default route to internet router) Host B (192.168.200.100): 192.168.2.0 gw 192.168.200.11 (network route through host C) 0.0.0.0 gw 192.168.200.17 (default route to internet router) For the return path, the internet router must have a network route: 192.168.2.0 gw 192.168.200.11 (through host C) Jim Cunning _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
