Hi everybody

I have one problem for the 1 dst-nat answer from 2 isp in Mikrotik RouterOS

I explain.

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.

Any help, idea or way?

is the route back setup correctly for the 2nd ISP? ie can you ping both public IP's from the internet?

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.
