Enabling Communication with Other Systems

If you use Network Address Translation (NAT) to assign a public IP address to your
VC400/VC120 system for communication with devices outside your private network, you
must enable NAT on your VC400/VC120 system before placing calls. For more information,
refer to
Network Address Translation on page 80 .

If your VC400/VC120 system communicates with other devices through a firewall, you
must configure your firewall to allow incoming and outgoing traffic to the VC400/VC120
system through the reserved ports specified in
Reserved Ports on page 78 . And the
required ports specified in Configuring the System for Use with a Firewall or NAT on page
77 . Users placing calls through a firewall to system may experience one-way audio or video
if the firewall is not properly configured.
