Destination Network Address Translation (DNAT) is a process that allows the placing of servers within the protected network
and making them available for a certain service to the outside world. The DNAT process running on the router translates the
destination address of incoming packets to the address of the real network server on the LAN. The packets are then forwarded.
You can Delete or Edit a DNAT rule after it has been defined and added by using the table at the bottom of the screen.

Select a protocol.
Select a network or host to which IP packets will be allowed and re-routed. The network/host
must be pre-defined in the Network Configuration section.
Select the External Service that you want allowed. The service must be defined in the Service
Configuration section.
Select the LAN IP to which the packets are to be diverted. Only one host can be defined as the
destination.
Select the Internal Service to be the destination.
Select the source address for packets that are going to be sent. If you do not want to change the
address, select NOCHANGE.
Click the Save button. The defined DNAT configuration is added and will display at the bottom of

IP Address = 192.168.2.100
Subnet Address = 255.255.255.255. The subnet mask in the network configuration is not
defined using x.x.x.x notation. It uses ‘bit’ notation. So 255.255.255.255 = 32.
