The following example configures an IPv4 network (intranet) with the subnet 192.168.80.0/24. The Internet provider has assigned a number of public IP addresses. Internet access has been set up using the Setup Wizard. Clients on the intranet are automatically masked behind the public IP address that was created with the Wizard.
Now we want to mask a server with the internal IP address 192.168.80.21 behind the public IP address 1.1.1.1.
The "return direction" of the masking, i.e. the server’s accessibility from the outside, is realized by a port-forwarding entry, which is not part of this example.
-
Create a new action object in the firewall under . Under Action, set the packet action to Transmit and the Policy-based NAT to 1.1.1.1.
-
Under create a new station object defined for the IP address 192.168.80.21.
-
Next, go to and create a filter rule.
-
In this filter rule, go to Actions and select the new action "SERVER-NAT" that was defined above.
-
Then go to Stations and use the newly created station object. If necessary. you can also specify the Internet line under Connection destination.
