I have a similar issue, the post doesn’t clarify one thing for me. Do I setup 2 WAN connections as if the other one was not there?

The process would be (making SFP2 into WAN2):

Add interface list item WAN2
Remove SFP2 from Bridge
Add SFP2 to WAN2 interface list
Add DHCP client to SFP2
IP > Firewall > Filters/NAT → add second rule like for eth0?

Are these the right steps? Then:

Add 2 IP Route
destination=0.0.0.0/0 gateway=WANgatewayIPofISP ping gateway distance=1
destination=0.0.0.0/0 gateway=WAN2-gatewayIPofISP distance=2

Anything else? Everything goes haywire when I try this so I stopped and want to gather some clearer instructions before I begin again since its a live connection.
