7008ABR – Manual

6.2.4 NAT

From this section you can configure the Address Mapping, Virtual Server, and Special Application features that provide control over the port openings in the router’s firewall. This section can be used to support several Internet based applications such as VPN connections.

•Address Mapping

This section allows you to configure one or more public IP addresses to be shared by multiple internal users. Enter the Public IP address you wish to share into the “Global IP” field. Enter a range of internal IPs that will share the global IP into the “from” field.

•Virtual Server

If you configure the Barricade as a virtual server, remote users accessing services such as web or FTP at your local site via public IP addresses can be automatically redirected to local servers configured with private IP addresses. In other words, depending on the requested service (TCP/UDP port number), the Barricade redirects the external service request to the appropriate internal server and port. The WAN interface should have a fixed IP address to properly utilize this function. For example, if you set Type/Public Port to TCP/80 (HTTP or web) and the Private IP/Port to 192.168.2.2/8080, then all HTTP requests from outside users will be transferred to port 8080 on 192.168.2.2. Therefore, by just entering the IP Address provided by the ISP, Internet users can access the service you provide at the internal address and port to which the Barricade redirects them.

Some of the more common TCP service ports include: HTTP: 80, FTP: 21, Telnet: 23 and

POP3: 110.
