The UT300R2U modem given by BSNL lately has a custom stripped down firmware. Almost all tutorials on port forwarding the modem assume you have the old firmware. This guide will show you how to forward your ports using the new firmware. If you are connecting to the internet using Bridged mode, you don't have to forward your ports. Port forwarding is necessary only if the router is working in PPPoE mode. If you would like to know more about port forwarding click here
