Chapter 3 - Configuring Network Use
Configuring the System for Use with a Firewall or NAT
A firewall protects your network by controlling data traffic from outside the network. Unless the firewall is designed to work with H.323 video conferencing equipment, you must configure the system and the firewall to allow video conferencing 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 is connected to a LAN that uses a NAT, you will need to enter the NAT public (WAN) address so that your system can communicate outside the LAN.
To set up the system to work with a firewall or NAT:
1.Go to System > Admin Settings > Network > IP > Firewall.
2.Configure these settings:
Setting | Description |
|
|
Fixed Ports | Lets you specify whether to define the TCP and UDP ports. |
| • If the firewall is not H.323 compatible, enable this option. The |
| V500 system assigns a range of ports starting with the TCP |
| and UDP ports you specify. The system defaults to a range |
| beginning with port 3230 for both TCP and UDP. |
| NOTE: You must open the corresponding ports in the |
| firewall. You must also open the firewall’s TCP port 1720 to |
| allow H.323 traffic. |
| • If the firewall is H.323 compatible or if the system is not |
| behind a firewall, disable this option. |
|
|
TCP Ports | Lets you specify the beginning value for the range of TCP and |
UDP Ports | UDP ports used by the system. |
| |
| NOTE: You must also open the firewall’s TCP port 1720 to |
| allow H.323 traffic. |
