Belkin wireless router. That will definitely have NAT protection. I use a Belkin myself but not the wireless version. UPnP on mine works ok unless it's been on days on end with heavy traffic then UPnP starts to fail sometimes. But wireless is much less reliable. Inconsistent speeds, inability to handle as much traffic messages, etc. Did you use this router before or after changing ISP/connection type?

As RobertR hinted, many Satellite services are not as reliable as other types of connection for p2p use. Usually less upload bandwidth. And some satellite services at least do shape or block p2p use.

In reference to the Gnutella.net file, for LW 5 simply delete it & LW will create a new one that should work (unlike LW 4.) However the fact neither of your p2p programs work suggests a problem at the hardware end & possibly the ISP.
