Let us assume two addresses (10.0.0.216 and 10.0.0.217) are assigned to the router. In this example we will 'full NAT' the internal address 192.168.0.4 to the external 10.0.0.216 one while keeping 10.0.0.217 for the router itself as well as for masquerading the internal network. To setup the router follow the. Very often you can see configurations where many firewall NAT rules are being used. Once you make one rule the whole principle is clear and you can easily add many of them. Quite often RouterOS users forget about interface parameter on these rules. The IP firewall is responsible for filtering packets (accepting or dropping them), as well as changing their properties. Three facilities exist: filter, mangle, and NAT.
