NOTE: The TCP start port and UDP start
port 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 with different UDPPORT
& TCPPORTs for each unit.
NOTE: If you have more than one Max
behind the same firewall you must repeat
the process for each unit opening a
different UDPPORT and TCPPORT for
each.
In Max-to-Max calling (when you call a Max unit from
another Max), if either Max is connected to a LAN that
employs a firewall, you will need to configure settings on
both the Max and the firewall before Max-to-Max calls can
be placed. This section will explain how to make the
necessary adjustments.
1. On the Firewall:
a. Open UDP Port 6801.
b. Open an additional UDP Port in the range of
21000-65535.
c. Open a TCP Port in the range of 4000 –
4015 for 8 ports and 4000 – 4031 for 16
ports. This must not be the same number
port you opened in the previous step.
(The maximum number in the range is
determined by the following formula:
Maximum = 4000 + (number of ports * 2) –
1.)
2. Access the Network Configuration Table on
Max’s Network and Voice Configuration page.
After opening the appropriate UDPPORT and
TCPPORT on the firewall (or having your
Broadband Service Provider open a port on the
