Alternate WAN ports

I recently purchased the hAP AC Lite and am using it as a travel router. Depending upon my connection options sometimes Ether1 is my WAN port and sometimes wlan1 is my WAN port. This requires a manual change to the routing and NAT settings.

Is there a way to set this up so whichever WAN interface pulls an IP to become the default route and Source NAT? They will never both be connected at the same time. These WAN interfaces are set to DHCP.

Leave both rules enable it works perfectly

So create a DHCP client, default route, and srcnat for both interfaces and the router will choose the connected interface?

Yes. That’s what i do and works fine.
