Hi everybody

I Have 2 ISP, 2 gateways, in the routerOs and one dst-nat for the 80 tcp port for one of my IP from my local network.

The nat only answer for ONE ISP, and i need anwer from 2 isp. I try mark paquets and routing from helps that explain multiples gateways forms, but DST-NAT dont work.

Use Mangle rule to mark incoming connections based off of the in-interface in both forward and input chain. Then on the output and pre-routing use those connection marks to mark for routing out the appropriate routes.
