2 WAN's, choose which to use

Hi,

I’m new to Mikrotik so I need some help in configuration. We are using 2 WAN and 2 LAN interfaces. All internet traffic goes through WAN1 for both lan’s with failover function to WAN2 and that works perfectly. Now I want to add Lan3 that should go out to the internet using only WAN2. I’ve added that LAN3 and the traffic for that network goes through WAN1 as for the other two. How to change that?

Hi
you have to make mangle and route with this options
/ip firewall Mangle
General
Chain:prerouting
In.interface:LAN3
Action
Action:Mark routing
New routing mark:To-WAN2
Passthrough:No
/ip route
Dst. Address:0.0.0.0/0
Gateway: WAN2
Routing mark:To-WAN2

do not forget Nat for WAN2
Best regards

It worked. Thank you!
