UDP Port 21000
The table below explains the procedure for opening firewall ports for your Max gateway. This example illustrates the UDP Port (OPAL) assignments (with a default start point of 7000) for a

In this example, the range to be opened is 7000 to 7015. The range is determined by the following formula:
Max Default Start Port + (Number of Max Ports * 2) – 1
or in this example:
7000 + (4*2) – 1 = 7007
The table shows the firewall port assignments based on the default start port. If the Max gateway default start ports noted above are in conflict with your corporate firewall settings, you may assign port numbers in the range of 4000 to 65000 by applying the same principle illustrated in the table.
The TCP Port and UDP Port start parameters in the Network Configuration table must match the open firewall ports.
If there are multiple Max gateways behind a firewall, this process must be repeated for each unit, using different UDP ports & TCP ports.
NOTE: The Net2Phone Max gateway will not work behind a proxy server.
