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.
