Hi Ryan,
Thanks for the tips. I found a wii network testing tool in the Nintendo 
support site. Had to fire up IE on a laptop to test, but it passed all 
the connection test going straight through m0n0wall. I was watching the 
m0n0wall firewall states, and could see it hitting the Nintendo site 
through many UDP and TCP ports during the test. So as far as I can tell, 
m0n0wall isn't so much the issue anymore. I wish I could figure out why 
the Wii will not go through it. The open linksys router down the street 
might have UPnP enabled, so that might be why it goes straight through 
it without issues, but as it has been said, I'm not a fan of the UPnP 
either, and as far as I can tell it shouldn't be necessary for the Wii 
to function since it only goes with outbound connections (no inbound as 
far as I know and from some google searching).

I haven't tried linking my laptop with the Wii and having it go through 
the shared connection yet, so if that works, I'll be sure to post it 
here for all to know in case anyone else encounters this issue.

Thanks!
Michael
