Hi Miguel, when you run GnuGk on your firewall, you usually have 2 interface, one to the LAN and one to the internet. Keep in mind that GnuGk must be able to do inbound and outbound connections for Q.931, H.245 and RTP on those interfaces, not just port 1720. This is usually done by defining port ranges in the GnuGk config and opening those ranges in the firewall. See the etc/proxy.ini example. If you want to keep all ports filtered in the firewall, place GnuGk outside the firewall and let your endpoints connect through the firewall using H.460.18/.19. Regards, Jan Miguel A.
