Administrator Guide

H323 NAT Address

Define the external/global IP address to the router with NAT support. Packets sent to the

router will then be routed to the system. Note that NAT cannot be used when registered to

a gatekeeper.
In the router, the following ports must be routed to the system's IP address:
* Port 1720
* Port 5555-6555
* Port 2326-2487

Requires user role: ADMIN
Default value: ""

Value space: String (0, 64)

A valid IPv4 address or IPv6 address.

H323 PortAllocation

This setting affects the H.245 port numbers used for H.323 call signaling.

Requires user role: ADMIN
Default value: Dynamic

Value space: Dynamic/Static

Dynamic: The system will allocate which ports to use when opening a TCP connection.

The reason for doing this is to avoid using the same ports for subsequent calls, as some

firewalls consider this as a sign of attack. When Dynamic is selected, the H.323 ports

used are from 11000 to 20999. Once 20999 is reached they restart again at 11000.

The ports are automatically selected by the system within the given range. Firewall

administrators should not try to deduce which ports are used when, as the allocation

schema within the mentioned range may change without any further notice.
Static: When set to Static the ports are given within a static predefined range [5555-

6555].
