Activating Network Address Translation (NAT)

NAT is enabled on the drop-in group interface that is connected to the gateway. Only the traffic from the private LAN will go through the NAT because of the option Remove from NAT (DMZ) which was set in the drop-in group configuration.

A list of all IP interfaces is displayed in the NAT interface menu.

Go to the following menu to enable NAT for your interface:

Go to Network -> NAT ->NAT Interfaces.

Network -> NAT ->NAT Interfaces

Proceed as follows:

Select NAT active for the LAN_EN1-4 interface. This is how the NAT feature is enabled for the interface.
Also select Silent Deny. When this function is enabled, attempts to access the LAN from outside are immediately rejected.
Confirm with OK.
