We have an 1811 router with apparently two WAN ports (fa0 and fa1) and 8 switch ports.
I only need the one WAN port. Is it possible to change fa1 into a switchport like fa2 through fa9?
If I run show interface fa1 switchport, I get fa1 is not a switchable port.
I would simply like to make it part of VLAN1 and be able to plug a PC into it like the others.

In the SDM configuration for that port, VLAN is not even an option; it's either static IP or dynamic IP.
