Hi, I have gnugk on my linux 2.4.20 firewall running iptables 1.2.7a with conntrack_h323 installed. >From within the LAN, netmeeting can register with gnugk and make calls to other registered endpoints (on LAN or Internet). >From the Intenet, netmeeting can register with gnugk but cannot make a call to endpoints in the LAN. I have been using ethereal to try and see what is happening. In both cases H.225 packets are exchanged between gnugk port 1719 <-> netmeeting port x and all looks fine. It seems that during call setup, the Internet netmeeting attempts to open a TCP connection to port 3000x on gnugk (the firewall) but contrack_h323 doesn't allow it. Anyone have any ideas whats wrong? or suggestions on how to debug my problem? One curious thing is that lsmod shows ip_net_h323 unused. Is this ok? ip_nat_h323 3392 0 (unused) ip_conntrack_h323 3136 1 ipt_MASQUERADE 2080 1 ipt_LOG 4192 3 iptable_nat 19988 2 [ip_nat_h323 ipt_MASQUERADE] ip_tables 13216 8 [ipt_limit ipt_state iptable_filter ipt_MASQUERADE ipt_LOG iptable_nat] Regards, Richard
