Natting among 3 connections

sunlinux · 09-10-2009, 01:39 AM

I have linux box with 2 eth cards and using as internet gateway configuring nating.. running fine.

Eth0: lan ip
Eth1:wan ip

Now my requirement is that I want to add another (different internet connection) new ip (alias) to Wan eth1. And route lan's request for destination tcp port 465 request to wan through this ip towards Internet. You may consider it somewhat load balancing .

pls write up.

Linux routing decisions are IP based, not port based. If the destinations are all to a common destination, you can add a route to that destination through the eth1:1 route. On the other hand, why put it on a different IP through the same network? That's not going to reduce any load.
