Hi Jan, thank you for the help. Reason for using 2.2.7 is that this is the packaged version with Ubuntu. Compiling the libraries from SVN/CVS head did not work, however the 'known good' lib combinations from Nov 16 compiles and runs cleanly. With this version I am having registration issues unfortunately. I used the following Routed/proxy config: [RoutedMode] GKRouted=1 H245Routed=1 EnableH46018=1 SupportNATedEndpoints=1 [Proxy] Enable=1 ProxyForNAT=1 ProxyForSameNAT=1 However registration for LifeSize and Merial does not go through. The NATed endpoints send a registrationrequest, receive a positive registrationConfirm...but try to register again after about 10 seconds. I confirmed this using a packet sniffer at the Endpoint (Wireshark: http://upload.xandrios.net/gnugk_2.3.1_reregistration_loop.pcap). I noticed that a Xmeeting endpoint does get registered. The difference between Xmeeting and LifeSize is that Xmeeting receives a data=noNAT in the nonStandardData field. Also, Xmeeting receives a serviceControl field with a sessionId=0, while Lifesize does not. A trace from a successful xmeeting registration from behind NAT can be found here: http://upload.xandrios.net/gnugk_2.3.1_registration_xmeeting.pcap Any advice on how to continue? Thank you! -Siet -----Original Message----- From: Jan Willamowius [mailto:jan@xxxxxxxxxxxxxx] Sent: Wednesday, December 23, 2009 5:38 PM To: openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Subject: Re: NAT issues with H245 Hi Siet, your first step should be to upgrade to GnuGk 2.3.1 and then enable H.460.18 in GnuGk and all your endpoints. The only problem will be the Mirial since it doesn't support any NAT traversal method as far as I know.
