Hi Bill, > i called the manufacturer > of the firewall and asked about the h.323 support and was told i need to > enable UPnP on my end to allow h.323 to work correctly. ehrm, there's no point where UPnP would help.. they probably meant UDP (which is the protocol type that's used for RTP streams, which transmit the payload of audio and video). if the opening of UPnP does help, they probably unblock whole UDP range, which is actually a solution, but not a very elegant one. *g* > hmm. this also explains (i think) why it was easier for him to call me but > more difficult for me to call him. and since the local network wouldn't go > through the router there was no problems testing on the lan. if you want to invest the effort, you can setup a VPN between you and your friend. then the whole firewalling is no issue anymore. but it's kinda overkill to do that "only for GM".. -- Best regards, Kilian
