AFAIK MSN sends informations like the local IP-address within the
payload of the voice chat request and therefor also MASQ will not work.
I don´t know exactly if it is based on h.323 if so perhaps the conntrack
module for h.323 helps. If not the possibilities are a working conntrack
module for these protocols, a UPnP aware router take a look at
http://sourceforge.net/projects/linux-igd/ or perhaps a proxy server on
the router. Got the similar problems here but didn´t have the time to
the opportunities.
