in PCC script in Mikrotik wiki or PBR script .. You have to mark the connection in both direction (Inbound - Outbound)
to make the reply goes back into the same WAN interface it left from
Do i really need to mark the inbound traffic ??
is that what routing table do to make sure the traffic goes into the same interface generated the request
So i could just put in mangle section -> mark outbound traffic (generated from LAN) then mark routing based on that connection mark
and Create a routing table for the WAN interfaces with the routing mark accordingly
Actually I'm curious to know whether it is critically important to mark the inbound traffic in multi wan environment or not necessary
