I have been messing around with this for a day now some success but not exactly what I want.
I have connections from 2 different isp. isp 1 serves me a dynamic IP, isp 2 gives me a /26. Isp 1 is a cable provider, lots of download (6mbit) but very little up 256-384K. Isp 2 is a t-1 provider, 1.5 mbit. What I was attempting to do was to send traffic out to the ineternet to isp 2 and have it return from isp 1. Then I read in the manual that policy routing does not work as expected on NATted interfaces since at the moment the packet is processed it has a source address of 0.0.0.0 ....
What I tried to do was masqerade all ip's to the dynamic address of isp 1 and send the traffic out the interface connected to isp 2 by making it the default route. I was unable to make it work can anyone help?
