Nat - D-Link DSA-3600 User Manual

Chapter 4. Web Interface Configuration

4.4.1 NAT

There are three functions that need to be set here: DMZ (Demilitarized Zone), Public Accessible Server and
Port and Redirect.
DMZ (Demilitarized Zone)
The administrator can define mandatory external to internal IP mapping using this function, so that a client on
the WAN side network can access the private machine by accessing the external IP. Choose to enable
Automatic WAN IP Assignment by checking the Enable check box and enter the Internal IP address. When
Automatic WAN IP Assignment function is enabled, accessing WAN1 will be mapped to access the Internal
IP Address. For Static Assignments, enter Internal and External IP Addresses as a set and choose to use
WAN1 or WAN2 for the External Interface from the drop-down menu. These settings will become effective
immediately after clicking the Apply button.
Public Accessible Server
The administrator can set up to forty virtual servers using this function, so that the computers not belonging to
the managed network can access the servers in the managed network via WAN1 port IP of DSA-3600. Enter the
External Service Port, Local Server IP Address and Local Server Port accordingly. Depending on the
different services selected, the network service will be able to use the TCP protocol or the UDP protocol. In the
Enable column, check the desired server to be enabled. These settings will be effective immediately after
clicking the Apply button.
