[TriLUG] iptables masquerading question

[Steve Kuekes]

Here's my answer to my own question....

I've got a solution that routes all the traffic from one of my internal 
ip's out the xxx.155 address using

-A POSTROUTING -o eth1 -s 192.168.1.59 -j SNAT --to-source xxx.xxx.xxx.155

This appears to work
