Max 410/420/430 User’s Guide – Chapter 5
38
Idle – CDR is not enabled
NOTE: If a default gateway address or a
DNS server address is not used the value
0.0.0.0 must be entered into their
respective boxes. If the boxes are left
blank the modified configuration settings
will not be saved.
REMINDER: Configuration changes you
make in the Max 410/420/430 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 52 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
In Max-to-Max calling (when you call any 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.
If your connection to the Internet utilizes a firewall, several
ports will have to be opened to allow your Net2Phone Max
gateway 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):
UDP Port (OPAL) 7000
TCP Port 4000
