3 . 1 . 1 a NAT Inbound (optional)
Inbound allows you to list or set up a series of rules to determine what will happen to the
incoming traffic. By default, all incoming packets other than packets arriving in response
to outgoing traffic, will be rejected.
The Interface (e.g. wan as shown in the dialog box below) listed in the table corresponds
to your configured WAN interface.
NAT should always be enabled only on the interface connecting to the
public network or WAN, not the interface connecting to the private network.
