For automatic port forwarding using UPnP to work, both the software and router must support this feature. Instead of connecting the router using a telnet client to view the text-based settings and manually typing commands to add a configuration, port forwarding is pretty much automatic these days thanks to Universal Plug and Play (UPnP). The solution is to forward the port which can be a daunting task for a lot of users as it needs the correct IP address, port number and transport protocol (TCP/UDP) or else it won’t work.įortunately the process of configuring port forwarding has gotten a lot easier through the years. It is generally safer but also creates a huge problem which is a lot of applications that work over the Internet might stop working. One of the main differences in using a router is your computer’s connection to the router is hidden behind it and not directly exposed to the Internet unlike using a modem. Nowadays most people are connected to the Internet using a router instead of a modem.
