Dual WAN failover

RouterOS Beginner Basics
1

Hi there,

I’m fresh new owner of CRS125-24G-1S-2HnD. I’ve set up it from scratch. I’ve create bridge (with ports 3-24), DHCP server, and it works.
I’m using ether1 and ether2 as WAN1 and WAN2 links. I’m getting configuration from my ISPs by DHCP. And it works for both WAN links.
However, I can’t create NAT for one of those links. I’ve created it sucessfully for one WAN port (WAN2). But when I’m creating NAT for WAN1 I’m getting error:
" in/out-bridge-port matcher not possible when interface WAN1 is not slave "
I’m not sure how to move forward with that.

I think the message is self-explanatory, you can’t use in/out-bridge-port (meant for ports in bridge) if interface is not part of bridge (that sounds right for WAN interface). I guess you probably want in/out-interface instead.
