Squid and PR_CONNECT_RESET_ERROR

I recently upgraded my home router and moved my 2100MAX to just another node on the LAN but squid now returns PR_CONNECT_RESET_ERROR when I connect to it using my browser. I wish to continue to use the proxy through ssh forwarding.

Of course it used to have LAN and WAN connected but now just WAN. No major changes, only changed the IP address from .254 to .253.

Googling for a solution really doesn't turn up much useful that I haven't already done.

Does the squid proxy have to have a WAN interface?
