4.4.5 ADVANCED - Port Forwarding
Port Forwarding:
Port Forwarding is necessary because NAT ( Network Address Translation ) only forwards
traffic from the Internet to the LAN if a specific port mapping exists in the NAT translation table. Because of
this, the NAT provides a level of protection for computers that are connected to your LAN. However, this also
creates a connectivity problem when you want to make LAN resources available to Internet clients, which you
may want to do to play network games or host network applications.
Thus Port Forwarding is necessary to run certain games, chat clients, video-conferencing and other kinds of
application. You might also need to configure port-forwarding if you intend to host a web server or mail server
that is to be visible outside your LAN.
