IP Pools NAT


On this page, you can define IP address ranges (public addresses) that will be used to NAT clients’ private IP addresses.


A new range can be added to the system by clicking on . Enter a network and its name. Define from which IP address IP addresses are to be offered. You may add reserved IP addresses, which will not be offered (+ Reserve IP address). Choose a particular locality. Finally, select the router or routers that will use a given IP address range. Finish the process by clicking on Save


When you are in the process of adding an Internet service in the Client card, you will be able to enter an IP address (a public address) from the range you have specified. If NAT is enabled, it is automatically done for a client’s private IP address on a given router.


To activate it, it is necessary to set the mikrotik_nat_for_end_user key to 1 in Settings Syst. settings Mikrotik. In the opposite case (value = 0), NAT is not done on the router. When you activate the function, a dstnat and srcnat rule will be added to the router for each client.
