11.5 The DMZ Screen

In addition to the servers for specified services, NAT supports a default server IP address. A default

server receives packets from ports that are not specified in the NAT Port Forwarding Setup

screen.

The following table describes the fields in this screen.

Open Start Port The open port is a port (or a range of ports) that a server on the WAN uses when it sends

out a particular service. The Device forwards the traffic with this port (or range of ports) to

the client computer on the LAN that requested the service.

Type a port number or the starting port number in a range of port numbers.

Open End Port Type a port number or the ending port number in a range of port numbers.

Open Protocol Select the transport layer protocol from TCP, UDP, or TCP/UDP.
