Max 8/16 and T1/E1 User’s Guide – Chapter 4
Page 23
NOTE: Configuration changes you make in the Max 8/16
or T1/E1 are not applied until you reset the unit. To do
this, you may either:
Go to the Restart System page (see Restart System
on page 46 in this Guide) and click Restart;
Type
/system/reset
at the command prompt; or
Power-off the unit, wait 10 seconds, and turn it on
again.
Configuring Firewalls
If your connection to the Internet utilizes a firewall, several ports will
have to be opened to allow your Max 8/16 or T1/E1 to make and
receive calls to other Net2Phone devices.
UDP Port 6801 must be opened. The following port types/ranges
must also be opened (the numbers displayed are the default start
points for each):
1. UDP Port (OPAL) 7000
2. TCP Port 4000
3. UDP Port 21000
The table below explains the procedure for opening firewall ports for
your Max 8/16 or T1/E1. This example illustrates the UDP Port
(OPAL) assignments (with a default start point of 7000) for an 8-port
Max 8/16 or T1/E1.
