This screen displays the IP addresses specified in the WAN screen (Network Configuration --> WAN from the left
menu). Up to eight WAN addresses can be associated with the switch. The NAT screen enables the administrator to set
of the type of translation and port forwarding required.
2. For each of the addresses, the select the NAT type.
• Select 1 to 1 from the pull-down menu to map a WAN IP address to a single local (subnet) IP address. This selection
is useful in situations in which users require dedicated IP addresses or when public-facing servers are connected to
the switch.
• Select 1 to Many from the pull-down menu to map a WAN IP address to a range of local IP addresses. Use this
option when there are fewer public IP address on the WAN than there are users on the LAN. 1 to Many NAT allows
a single IP address to handle traffic from multiple private LAN IP addresses.
• Select None from the pull-down menu when the administrator sets up routable IP addresses (set on the Network
Configuration --> Routing screen).
3. If the NAT type is 1 to 1, the Outbound Mappings field allows the administrator to specify a single IP Address. This
address specifies the 1-to-1 mapping between the WAN IP address the specified LAN IP address.
4. If the NAT type is 1 to Many, the 1 to Many button in the adjacent Outbound Mappings field is active, allowing the
administrator to specify address assignments for each subnet. If no translation should be done, none should be selected
for the subnet.
