Port Forwarding
In addition to this IP address you must also configure your DSL or cable modem to understand that a
connection to it from a specific port number should have those requests sent to the Gateway. This is
called “port forwarding”. Configuring this is different for each network and is beyond the scope of this
user guide. There are excellent references on the internet that may help you configure your specific
hardware.
This is a screen image from a CenturyLink DSL modem. The gateway is on port 2101 and its internal IP
address is 192.168.0.52.
Port Forwarding makes it possible for a remote application to connect to this network using a name (by
way of the DynDNS service) and then directs any traffic to/from port 2101 to the Gateway.
