NAT
The NAT function supports 3 types of network address translation
DMZ (Demilitarized Zone)
Public Accessible Server
IP/Port Forwarding
DMZ (Demilitarized Zone)
The system supports specific sets of Internal IP address (LAN) to External IP address (WAN) mapping in the
Static Assignments. The External IP Address of the Automatic WAN IP Assignment is the IP address of
External Interface (WAN1) that will change dynamically if WAN1 Interface is Dynamic. When Assign WAN
IP Automatically is checked, the entered Internal IP Address under will be bound to the WAN1 interface.
Each Static Assignment could be bound with the chosen External Interface, WAN1 or WAN2. There are
specific sets of static Internal IP Address and External IP Address available. Internal and External IP
Addresses are entered as a set. After the setup, accessing the WAN will be mapped to access the Internal
IP Address. These settings will become effective immediately after clicking the
Apply
button.
Public Accessible Servers
Public Accessible Servers allow the administrator to set virtual servers, so that client devices outside the
managed network can access these servers within the managed network. Different virtual servers can be
configured for different sets of physical services, such as TCP and UDP services in general. Enter the
“External Service Port”, “Local Server IP Address” and “Local Server Port”. Select “TCP” or “UDP” for the
service’s type. In the Enable column, check the desired server to enable. These settings will become
effective immediately after clicking the
Apply
button.
