Even though I'm new to this list, I think that this should probably be addressed by Jozsef Kadlecsik. Jozsef, I've read a couple of your posts on this list that seem to indicate that there is a known incompatibility between your h323 conntrack module and the openh323 libraries. Is this accurate? If so, are there any plans to address this incompatibility? I've been unable to get the GNU gatekeeper functioning correctly behind an iptables firewall for possibly this reason. Thanks! p.s. Btw, I tried emailing you about this but it was bounced saying that your MTA rejected my email saying my site was banned because of unsolicited email. I can assure you that there has never been one single spam emanating from my site ever. And if you're banning my ISP - Comcast - you've just banned the majority of broadband users in the US.
