Hello I am trying to connect Netmeeting from behind a firewall to another PC with a external public IP with 50% success. The firewall is Bering 1.0, kernel 2.4.18, iptables 1.2.6a and shorewall 1.3.10. I included ip_nat_h323.o and ip_conntrack_h323.o modules of Jozsef Kadlecsik. +-----+ | | +-----+ Internal PC IP 192.168.1.11. | LAN +-----+ Firewall internal gateway IP 192.168.1.254. | | +-----+ Firewall external IP 200.45.218.203 | Internet +-----+ Other PC Public IP | | +-----+ Audio and video Netmeeting incoming calls does work well, from a PC with public IP to my private IP. Outgoing calls doesn't work, from my private IP to a public IP. In the other PC appears a message like "Waiting confirmation from 192.168.1.11", but in my netmeeting doesn't appears any message. I think this IP should be the public IP of firewall 200.45.218.203. I run tcpdump on interface ppp0, but no private IP 192.168.1.11 appears, only the public IPs. What could be the problem? Regards Heriberto
