4.6.1 Port Range
You want to share resources on your PC with your friends who are not in your LAN. But,
by default, the router's firewall blocks inbound traffic from the Internet to your computers
except replies to your outbound traffic. You can use the Port Forwarding feature to create
exceptions to this rule so that your friends can access these files from external networks.
When accessing your PC from Internet, type "protocol://xxx.xxx.xxx.xxx:port number" into
your browser’s address or location field. The protocol and port are the ones used by the
service and "xxx.xxx.xxx.xxx" is the WAN IP address of your router. For example, a FTP
server uses the ftp protocol and 21 (standard port number).
