As usual, when I have some time off, I tinker with my network and tend to break something.

I decided that I could let my wireless router rest a bit by turning off its gateway functionality, thereby accepting it into my LAN and telling it not to treat the other side like the wilds of the Internet. This means it wasn’t translating addresses for me anymore. No NAT.

This is all well and good, but now the network on the other side of that wireless router needs to be known to my central Linux router. Hmmm!

So, I typed in

sudo /<span>sbin</span>/ip route add via dev eth2

where is the wireless network and is the tiny (2 connection) network between the Linux router and the wireless router.

In CentOS 3, this information is stored in the /etc/sysconfig/static-routes file like so:

any net netmask gw dev eth2
