Polycom PVX with firewall

1. Configuring for use with firewalls

The following ports must be opened in the firewall and assigned to the videoconferencing endpoint(s):

  • Port 389 (TCP): For ILS registration
  • Port 1503 (TCP): Microsoft NetMeeting T.120 data sharing
  • Port 1718 (UDP): Gatekeeper discovery
  • Port 1719 (UDP): Gatekeeper RAS (Must be bi-directional)
  • Port 1720 (TCP) H.323 Call setup (Must be bi-directional)
  • Port 1731 (TCP): Audio call control (Must be bi-directional)
  • Ports 3230-3235 (TCP/UDP): Signaling and control for audio, call, video and data/FECC
  • Port 3603 (TCP): ViaVideo Web interface (ViaVideo users only)

2. Windows Internet connection firewall

Enabling Windows XP's Internet Connection Firewall can interfere in PVX's ability to place or receive video calls.

Complete the following steps to correct:

  1. Go to Start then Control Panel then Network Connections.
  2. If more than one connection is present, choose the one that is used with the PVX. This will most likely be the same connection that the PC uses for general IP traffic. This process may need to be applied to all connections.
  3. In Local Area Connection Properties, select Advanced.
  4. Clear the Internet Connection Firewall option.

If a firewall is still required, an external or software firewall with the ability to open specific ports for H.323 traffic is recommended.
