IT Admin Guide:

AVC is a hosted video conferencing service. The client software is run on a PC and communicates with centralized servers.

 

Network Setup

If your routers/ firewalls have the following settings, they must be disabled:
 

  • Any SIP settings, including a SIP application layer gateway (ALG)
  • Stateful packet inspection (SPI) firewall
     

*We have found that most Juniper brand networking equipment has this on by default. If you have Juniper routers and/or firewalls, please disable the above.

 

Firewall Setup

If your firewall does not block outbound traffic, AVC will work without further setup. But if your policy requires that all outbound traffic is blocked unless exceptions are made, the following are three different ways to configure your firewall to support AVC.

Option 1:

Allow all ports (TCP & UDP) outbound for 69.54.76.0/24

This setup requires the least amount of future maintenance.
 

PROTOCOL

OUTBOUND PORT

DESTINATION IP

TCP and UDP

All

69.54.76.0/24

(Table for Option 1)

Option 2:

Allow all ports (TCP and UDP) outbound for the range 69.54.76.1 to 69.54.76.33

This setup may require future maintenance as IP address are added.

 

PROTOCOL

OUTBOUND PORT

DESTINATION IP

TCP and UDP

All

Range: 69.54.76.1 - 69.54.76.33

(Table for Option 2)

Option 3:

Set up the following ports and range of IP addresses for allowed access

This setup is the most granular, but ports and IP addresses are subject to change and could cause connectivity problems in the future.
