Gateway behind a NAT/Firewall Network
The VoIP gateway uses a private IP address and the Internet sharing function of other systems to connect
to the Internet.
The following diagram shows a typical network connection in which broadband devices such as an
ADSL router work in router (NAT) mode so that the gateway is behind a NAT/Firewall. In this case, the
broadband router (NAT/Firewall) and the gateway need to be configured correctly in order to allow the
gateway to communicate with the Internet and VoIP network properly, using different techniques to
traverse the NAT/Firewall.
The table shown on the next page lists possible solutions for different network scenarios.
