14 NAT Mappings
The configuration of NAT Mappings allows the IP address mapping of all inbound and outbound NAT’ed
traffic to and from an internal client IP address.
The settings to configure NAT Mappings are located at: Network > NAT Mappings
To add a rule for NAT Mappings, click Add NAT Rule, upon which the following screen will be displayed:
NAT Mapping Settings
LAN Host
This is the IP address of the host on the LAN that the system should map the selected
connection IP address correspondences.
Inbound
Mappings
This setting specifies the WAN connections and corresponding WAN-specific Internet IP
addresses on which the system should bind on. Any access to the specified WAN
connection(s) and IP address(es) will be forwarded to the LAN Host.
Note 1: Inbound Mapping is not needed for WAN connections in drop-in or IP forwarding
mode.
Note 2: Each WAN IP address can be associated to one NAT Mapping only.
Outbound
Mappings
This setting specifies the IP address of each WAN connection to be used for any outgoing
traffic originating from the LAN Host.
Note 1: If you do not want to use a specific WAN for outgoing accesses, you should still
choose default here, then customize the outbound access rule in the Outbound Policy section.
Note 2: WAN connections in drop-in or IP forwarding mode are not shown here.
Click Save to save the settings when configuration has been completed.
Important Note
Inbound firewall rules override Inbound Mapping settings.
