I am hoping that some will be able to help with the following issue I am having on what seems to be a derivative of Red Hat.

I want to have an interface eth0, eth1 and eth0:1 on the same subnet:



default gateway

I want to connect to different web servers, say and, but I want to force the originating IP address.

So, I want to get a routing table that looks like:

Dest Mask Gateway Interface eth1 eth0:1 eth0
(plus the usual ones)

So I can quite easily set this up and it works with the physical interfaces. However, I am having difficulties adding the eth0:1 route.

When I do "route add -host gw dev eth0:1" the line appears but with the "eth0" interface.
I do not believe the request will originate from the desired IP address.

Any ideas or pointers would be fantastic.

Thanks in advance.

Since eth0 and eth0:1 are on the same subnet I do not not see what you are trying to accomplish.
