I saw this on the page, use the wan as lan.
Then could it be support that use the lan as wan?
Yes. Both the port can be used as WAN or LAN.
But using lan port as WAN is not in the UI because of it is complicated. When you have multiple WAN you need to create different zone and firewall rules, setting up routing policies etc. So pls do this in Luci or modify the settings direction.
Thanks, that useful!
