Description
Gateway(config)# applications
port-forwarding
Enable Port Forwarding function. A host
on the private network of the Residential
Gateway is invisible from the Internet for it
is protected by the firewall. Therefore,
when a server is on the private network,
its service will be inaccessible from the
Internet. To open the service to hosts on
the Internet, the network administrator
may adopt Port Forwarding feature. Port
Forwarding allows an IP address on the
private network to be accessed from an IP
address on the public network. It will
redirect packets from the public network
to a specified private IP address if the
packets meet the pre-condition of a port
forwarding rule.
