 NAT Type: It specifies the type of the NAT rule. The available options are EasyIP,
One2One, and Passthrough. Here please select Passthrough.
 Start Internal IP Address and End Internal IP Address: They specify the internal
address range of the NAT rule. They are usually public IP addresses provided by the
ISP. The LAN hosts that belong to this address range will use the Passthrough NAT
rule; that is, the Device will not perform NAT for them, so the packets sent by these
hosts to the outside hosts will be directly routed and forwarded. Note that the internal
address range of a Passthrough NAT rule should not overlap with the external
address range of any EasyIP or One2One NAT rule.
 Bind to: It specifies an Internet connection to which the NAT rule is bound. The LAN
hosts that match the NAT rule will access the Internet through this Internet
connection.
 Description: It specifies the description of the NAT rule.
¾ Save: Click it to save the NAT rule settings.
