iptables outgoing adress using an aliased interface

tniemela · 12-15-2010, 10:26 PM

Hi, it´s been several years since i played with iptables. I have setup like this:

eth0 is the only physical device on box and eth0:0 is aliased. Traffic going out of the box to internet uses eth0

eth0 116.55.58.1
eth0:0 116.55.58.2

I have a service listening on port 80 on 116.55.58.2

Lets say my client connect to 116.55.58.2:80 through 116.55.58.1 , how do I force (mangle you name it) with iptables that the outgoing source address will be always 116.55.58.2?

Thanks

You checked, that for now the outgoing source address is 116.55.58.1 even when .2 was addressed?
