NAT Mapping Settings

LAN Client(s)

NAT Mapping rules can be defined for a single LAN IP Address, an IP Range, or an

IP Network.

Address

This refers to the LAN host’s private IP address. The system maps this address to a

number of public IP addresses, specified below, in order to facilitate inbound and

outbound traffic.

This option is only available when IP Address is selected.

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.

This option is only available when IP Address is selected in LAN Client(s) field.

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.

Range

The IP range is a contiguous group of private IP addresses used by the LAN host.

The system maps these addresses to a number of public IP addresses, specified

below, to facilitate outbound traffic.

This option is only available when IP Range is selected.
