The firewall allows access to the local network by opening ports to certain types of packets usually based on IP addresses or protocol types. When traversing a firewall, the H.323 protocol requires the use of certain static ports as well as a number of dynamic ports that are selected at random from a very wide range. Without some other technical solution, it would be required that all ports within this wide range be kept open to bi directional traffic. This paper first describes in more detail the technical relationship between the H.323 protocol and firewalls. Then paper describes multiple possible solutions.
