2.5.7 Setting Firewall Parameters

Ensure that the firewall settings are applicable to the H.323 videoconferencing system.
Otherwise, the system and the firewall will need to be configured to allow the video conference
to pass the firewall.
Context
The firewall protects your IP network by preventing harmful data being passed between the
internal and external networks. Ensure that the firewall settings are applicable to the H.323
videoconferencing system. Otherwise, the system and the firewall must be configured to allow
the video conference data to traverse the firewall.
Using Network Address Translation (NAT) technology, a device within the LAN can use a
dedicated internal IP address and an external IP address that can be used for communication
with external devices. If your LAN uses NAT technology, set the IP address of the NAT public
network for the terminal.
Procedure
Step 1 Choose Settings > Network > IP > Firewall, and then set the parameters listed in
Table 2-9 Firewall parameters
Parameter
Enable H.460
Use NAT
NAT address

Description
If slight lip synchronization problems persist after the network jitter is
adjusted, adjust this parameter slightly.
Description
The private network accesses the public network using the NAT device.
Thus, if the terminal is installed in the private network, you need to
select one of the following options as required so that the terminal can
call the videoconferencing system or other terminals in the public
network:
l When the HUAWEI 9000 communicates with the other vendors'
devices, select Enable H.460.
l When the HUAWEI 9000 communicates with Huawei devices,
select Use NAT or Enable H.460. It is recommended that you select
Use NAT.
If Use NAT is selected, set the IP address of the terminal in the public
network.
