I have two interfaces on a centos machine with IPs 192.168.2.15 and 192.168.3.15. The routing table is: # route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.3.0 * 255.255.255.0 U 0 0 0 eth1 192.168.2.0 * 255.255.255.0 U 0 0 0 eth0 169.254.0.0 * 255.255.0.0 U 0 0 0 eth1 default 192.168.2.1 0.0.0.0 UG 0 0 0 eth0 The gateway 192.168.2.1 is a wireless router on which I have a static route for 192.168.3.0/24 to 192.168.2.15. The problem is I cannot communicate between these networks. If I ping from a machine on 192.168.2.0 to a machine on 192.168.3.0 it never makes it. If I run tcpdump -i eth0 on the machine with two nics, I can see the ICMP packets coming in so I know the static route on the wireless router is working. If I run tcpdump -i eth1 I cannot see the ICMP packets. So the routing is wrong. I can successfully ping the machine on the 192.168.3.0 network from the machine with two interfaces. I would think that a packet sent from 192.168.2.100 for 192.168.3.128 would go to the gateway, get sent to 192.168.2.15 which it would go though the above listed routing table, match 192.168.3.0 and get sent to eth1. What am I doing wrong? Mike -- Michael B Allen PHP Extension for SSO w/ Windows Group Authorization http://www.ioplex.com/
