NAT, or Network Address Translation is important on a router because it lets multiple devices on a local network share a single public IP address when accessing the internet. This saves IP addresses and allows all your devices to connect online. NAT also adds security by hiding your devices’ private IP addresses from the outside world, making it harder for attackers to directly target them
To configure NAT
Open Winbox -> Click on IP-> Select Firewall-> Click the NAT tab-> Select the Plus button
