Utilizing the WAN port as a 2nd LAN port

[jebbgrenham]

Has anyone explored the feasibility of this or accomplished this?
cfw ^.* doesn't seem to expose a way to do this easily.

I think it's unlikely to be easy- the devices are expected to be used routing-wise with the WAN port, but best of luck if you do experiment.
