Advanced>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.
