Archer C7: Can WAN-port be used as LAN-port?

Installing and Using OpenWrt

OpenWrt 18.06.1

I don't need the WAN-port of a TP-Link Archer C7 v5 and would like to have a 5th LAN-port instead. Is this possible?

Using Luci: Network / Switch I couldn't find what I am searching.

Yes, all ports of the c7-v5 are members of the same switch - so you can remove the WAN interface and add it to the LAN VLAN with the switch configuration.

Thanks, but I have no idea how to assign LAN. I clicked add, which you see empty in row 3 in the screenshot. WAN was not visible before. So I removed nothing.

I don't know how VID3 gets in there, but you can delete VLAN 2 and 3 - and then 'guess' what to do about WAN for VID 1.

VID 3 was created, when I clicked add, it is not there and I didn't save it.

Edit;
I think I understood it, Removing VID2 removes the WAN functionality and Untagged at VID1 in WAN column adds LAN functionality.
