I seem to have got myself completely lost in trying to figure out port forwarding to enable video conferencing. We have a server with two NIC cards running Fedora 12: eth0 is connected to the internal network and has a fixed private IP address of 10.1.4.73. eth1 is connected to the internet and has a dynamic public IP address. The videoconferencing equipment has a fixed IP address of 10.1.0.14 (default gateway 10.1.4.73). The remote border controller has an IP address of 217.3.2.254. The requirements are that the following ports are forwarded in an outbound direction to 217.3.2.254: 1719 UDP 1720 TCP 2776 TCP 2776 UDP 2777 UDP 2777 TCP I know that this should be very straightforward, but I've got myself totally confused!
