Thanks for the response Jan! Do you mean to give a PC with GnuGK an external IP address? I'm afraid this is not really an option for us, since we have a single internet connection which goes through series 800 cisco router. Everything behind the router is on non-routable segments (192,168.*.*). So I guess then I will have to provide static NAT mapping for gatekeeper related ports ... :-( Best regards, 14.10.2015 23:02, Jan Willamowius пишет: > Hi Mikhail, > > I haven't used H.323 support in a Cisco 800, but the general advice is > not to rely on H.323 helpers in NAT routers, but to place a GnuGk in > front of the NAT router and to use the H.323's NAT traversal protocols > (H.460.18/.19) instead. > > Regards, > Jan > -- \ / | | (OvO) | Михаил Иванов | (^^^) | Тел.: +7(911) 223-1300 | \^/ | E-mail: ivans@xxxxxxxxxxx | ^ ^ | | ------------------------------------------------------------------------------ _______________________________________________________ Posting: mailto:Openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Archive: http://sourceforge.net/mailarchive/forum.php?forum_name=openh323gk-users Unsubscribe: http://lists.sourceforge.net/lists/listinfo/openh323gk-users Homepage: http://www.gnugk.org/
