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
