How to Open Ports in a MikroTik Router

Configure the MikroTik Linux-based router to protect your private network while also allowing access to services you wish to provide over the computer network. The MikroTik router features an application-based configuration module that can be accessed directly through a Web browser. Use the “Winbox” application to add port forwarding to the MikroTik router configuration.
