Thread seems outdated but it covers my question exactly. Didn't find any solution anywhere else yet.
If anybody who got this (asuswrt (merlin) port forwarding through PIA) to work, please let us know :)
Just bought the RT-AC3200 to replace the horrible router that was given by my fiber provider.
I use PPPoE and the fiber modem delivers tagged traffic on VLAN 6.
Is it possible to configure VLAN for the WAN port on this router?
Might be off topic, but VLAN on the WAN interface is exactly what I need. Do you know how to configure this in asuswrt? Or is other firmware necessary?
