Hi.

I have two ADSL lines, and I want to use the two bandwith on my network.
I created the first ADSL as an interface it works well, but the second didn't. It doesn't connect. The 0.0.0.0/0 rule use the first ADSL.

So I decided I create NAT rules for each subnet and then I can NAT the traffic to the ADSL what I want. But I can't do it.
Do anyone know how can I do this ?
Or a solution, how can I use multiple ADSL transparently to the users ?

Read the manual first (see examples even). Then search the forums. It has been explained 100's of times here.
