Chapter 3 - Configuring Network Use

Configuring the System for Use with a Firewall or NAT

A firewall protects an organization’s network by controlling data traffic from outside the network. Unless your firewall is designed to work with H.323 videoconferencing equipment, you must configure the system and the firewall to allow videoconferencing traffic to pass in and out of the network.

Network Address Translation (NAT) network environments use private internal IP addresses for devices within the network, while using one external IP address to allow devices on the LAN to communicate with other devices outside the LAN. If your system uses a NAT, it must be assigned a public IP address to communicate outside the LAN.

To set up the system to work with a firewall or NAT:

1.Go to System Info > Admin Setup > LAN/H.323 > LAN/Intranet > Firewall/LAN Connection.

2.Configure these settings:

This enables the ViewStation system to assign a range of ports

 

starting with the TCP and UDP ports you specify. In most cases,

 

the range begins with port 3230 for both TCP and UDP.

 

Note: You must also open the firewall’s TCP port 1720 to allow

 

H.323 traffic.
