The complete network path connecting two H.323 terminals must have a constant available bandwidth for the whole duration of the connection. The effective bandwidth used on LAN/WAN Full-Duplex network connections is equal to the sum of the Audio Rate and Video Rate, plus approximately 20% for TCP/IP overhead.

  • Page 83: Nat - Firewall Interoperability

    NAT – FIREWALL Interoperability Introduction There are many strategic advantages for companies that succeed in making all traffic converge from voice applications, video and data to one IP network infrastructure. Unfortunately, the drive to concentrate all IP communications onto one single network has reduced. The connection between a company’s corporate network and the Internet world is accomplished with firewalls and devices using NAT (Network Address Translation), which block voice and video calls via IP.
  • Page 84 Firewalls Companies that allow connection to the Internet by their employees typically install a firewall in order to prevent external access of or tampering with internal data. The firewall examines the destination IP address and port number of every packet received from outside. Usually, firewalls are configured in such a way that if a computer from inside the firewall requests data from a computer outside the firewall, the response packets will be allowed through from the external computer, but only if they are sent to the IP address and port of the internal computer that generated the request.
  • Page 85 The Stargate router also supports NAT functionality and is therefore capable of substituting the public NAT address for the private IP address automatically inserted in the H.323 payload packets by the internal terminal.
