Got it, thanks Damion It was so easy to think in using directly ethx:y in iptables :( Anyway,my point is that i need to do SNAT in a three ISP environment with multipath routing to balance the outgoing traffic. So far i decided to go with separate Ethernet cards so i will go back to the aliasing thing later. Now i will do NAT with iptables in separate cards in POSTROUTING chain (after routing decision has taken). By the way, what's the behaviour of multipath routing if one of the providers goes down ? Should i take care manually to take it out from the multipath ?
