The H323 settings

H323 NAT Mode
The firewall traversal technology creates a secure path through the firewall barrier, and enables
proper exchange of audio/video data when connected to an external video conferencing system
(when the IP traffic goes through a NAT router). NOTE: NAT does not work in conjunction with
gatekeepers.
Requires user role: ADMIN
Value space: <Auto/On/Off>
Example: H323 NAT Mode: Off
H323 NAT Address
Enter the external/global IP-address to the router with NAT support. Packets sent to the router will
then be routed to the system.
In the router, the following ports must be routed to the system's IP-address:
* Port 1720
* Port 5555-5574
* Port 2326-2485
Requires user role: ADMIN
Value space: <S: 0, 64>
Example: H323 NAT Address: ""
H323 Profile [1..1] Authentication Mode
Set the authenticatin mode for the H.323 profile.
Requires user role: ADMIN
Value space: <On/Off>
Example: H323 Profile 1 Authentication Mode: Off
38
Password protection
Auto: The system will determine if the "NAT Address" or the real IP-address should be used
within signalling. This is done to make it possible to place calls to endpoints on the LAN as well
as endpoints on the WAN.
On: The system will signal the configured "NAT Address" in place of its own IP-address within
Q.931 and H.245. The NAT Server Address will be shown in the startup-menu as: "My IP
Address: 10.0.2.1" .
Off: The system will signal the real IP Address.
Format: String with a maximum of 64 characters.
On: If the H.323 Gatekeeper Authentication Mode is set to On and a H.323 Gatekeeper
indicates that it requires authentication, the system will try to authenticate itself to the
gatekeeper. NOTE: Requires the Authentication LoginName and Authentication Password to be
defined on both the codec and the Gatekeeper.
Off: If the H.323 Gatekeeper Authentication Mode is set to Off the system will not try to
authenticate itself to a H.323 Gatekeeper, but will still try a normal registration.
