NAT Configuration allows you to host internet applications when NAT is enabled. You can host different
games and software on different PCs.
◆
Pinhole Entry allows you to transparently route selected types of network traffic, such as FTP requests or
HTTP (Web) connections, to a specific host behind the Gateway. Creating a pinhole allows access traffic orig-
inating from a remote connection (WAN) to be sent to the internal computer (LAN) that is specified in the Pin-
hole page.
Pinholes are common for applications like multiplayer online games. Refer to software manufacturer applica-
tion documentation for specific traffic types and port numbers.
◆
Determine if any of the service applications that you want to provide on your LAN stations use TCP or UDP
protocols. If an application does, then you must configure a pinhole to implement port forwarding.
• Protocol: UDP or TCP
• External Port Range: This is the range of ports on which you expect incoming traffic to be received.
• Internal Address: This is the internal host IP address to which you want the traffic to be directed.
• Internal Start Port: This is the port number at the start of the port range that you want your Gateway to use
when forwarding traffic of the type(s) you have selected to the internal IP address.
