(BHi
(B
(BAll I had set up, except the 5000-5016 UDP ports forwarded to the Gnomemeeting
(Bbox. The Netmeeting has an open way to it from the router, as it has DMZ set
(Bup. Now I opened the ports 5000-5016 toward the Gnomemeeting box, and I can
(Btest it tomorrow. Is there a chance that this was my problem? All the other
(Bports were already opened and as I said, the Netmeeting has no protection
(Bwhat so ever.]
