Ahh BUT the MSN *server* is sitting outside of your natted network and
when it does a getaddress() method or whatever, your firewall/NAT
returns the real IP address and not the "Natted" address. So in short,
if you want this to work "like MSN" your server will need a REAL
ipaddress and not behind a NAT.
