Question / Issue:

I have the following route table but want the default traffic to go out eth0. How do I change this? # route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 192.168.3.1 0.0.0.0 UG 0 0 0 eth2 192.168.0.0 * 255.255.255.0 U 0 0 0 eth0 192.168.3.0 * 255.255.255.0 U 0 0 0 eth2 192.168.5.0 * 255.255.255.0 U 0 0 0 wlan0 192.168.6.0 * 255.255.255.0 U 0 0 0 eth1

Assuming your gateway on eth0 is 192.168.0.1, try this: # ip route replace default via 192.168.0.1 Your routing table should look like something like this: # route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 192.168.0.0 * 255.255.255.0 U 0 0 0 eth0 192.168.3.0 * 255.255.255.0 U 0 0 0 eth2 192.168.5.0 * 255.255.255.0 U 0 0 0 wlan0 192.168.6.0 * 255.255.255.0 U 0 0 0 eth1
