I'm using a Satori'ed WRT54G with a separate ADSL modem (in the UK). This modem is providing a 1-port NAT, with internal IP 172.16.0.1, and is set to DMZ to my WRT54G which has IP 192.168.0.1. I know this is some kind of 'double-NATting', so does this mean I can't use uPnP at all on the WRT54G? If so, any idea how to get things like MSN messenger audio to work - does the Satori firmware have any features which could help me? Thank you!
