How to mark SRC Connection to Deliver from that

RouterOS General
1

I have a Routerboard 750GL with 2 WAN’s.
The first one, on ETH1 is my default gateway, and all my Internet Traffic from inside my LAN is routed by that (0.0.0.0/0 by eth1).

I have another WAN at ETH4, and i just want that when that ETH4 receives a packet, the response goes from the ETH4. I can’t do that. Now, when a packet comes from ETH4, Mikrotik routes the answer from ETH1. How can i make the packet received from ETH4 to be answered from ETH4?

Kind Regards,

You are going to need to set up policy based routing for that. If you look at the PCC wiki page, there is an example in there that you can modify to your needs.
