Port Forwarding
Port forwarding enables you to direct incoming traffic to specific LAN hosts (computers on your network) based on
the protocol and port number. It is used to play Internet games or provide local services (such as web hosting) for
a LAN group. Port forwarding is also referred to as “virtual servers.” You can:
• Apply predefined port forwarding rules to one or more computers
• If you have the necessary networking knowledge, create, edit, or delete your own port forwarding rules
• Add a computer to the DMZ
