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?
