Client(s) 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.
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.
Network
The IP network refers to all private IP addresses and ranges managed 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 Network is selected.
Inbound
Mappings
This setting specifies the WAN connections and corresponding WAN-specific
Internet IP addresses on which the system should bind. 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 the
LAN
Client(s) field.
Note that inbound mapping is not needed for WAN connections in drop-in mode
or IP forwarding mode. Also note that each WAN IP address can be associated
to one NAT mapping only.
Outbound
Mappings
This setting specifies the WAN IP addresses that should be used when an IP
connection is made from a LAN host to the Internet. Each LAN host in an IP range
or IP network will be evenly mapped to one of each selected WAN's IP addresses
(for better IP address utilization) in a persistent manner (for better application
compatibility).
Note that 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. Also note that WAN connections in drop-in mode 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 the
Inbound Mappings
settings.
