<p class=MsoNormal>Hey everybody;<br>
<br>
I don't know why I'm having a brain fart, but after trying to remember how to
go about this, I figured I'd see if some wiser heads can prevail in helping
out.<br>
<br>
Here's the situation: <br>
<br>
I have one linux box that is the final destination for three distinct networks
all arriving via different interfaces. Example:<br>
<br>
Eth0 - 192.168.1.x<br>
Eth1 - 12.24.9.x (made up examples)<br>
Eth2 - 64.29.223.x (made up example)<br>
<br>
These interfaces are connected to different providers.<br>
<br>
The short question - How can I set up the routing tables so that traffic
received on Eth1 leaves via eth1 and traffic received via eth2 leaves via eth2?
<br>
<br>
What's happening now is that when I make a request for service on one of eth1 or
eth2, the packet wants to leave on the default gateway for the box, which is
connected to eth0.<br>
<br>
<br>
Thanks<br>
<br>
Brad<o:p></o:p></p>
