Introduction
Port forwarding enables programs or devices running on your LAN to communicate with other devices on the internet as if they were
directly connected. Many internet services and applications use designated ports and when packets arrive at the router, they will be lost
unless they are directed to the appropriate destination. Port forwarding works by forwarding a specific TCP or UDP port or range of ports
from the modem/router to the computer or device you are using.
There might also be times when you wish to place a device connected to your router in the “demilitarized zone” or “DMZ”. A device placed
in the DMZ will have all port numbers forwarded to it, giving it unrestricted access to the internet.
Important
–
Each service or application generally uses different TCP or UDP ports. Refer to the documentation for the service or application to find out
which ports need to be forwarded.
You can only forward a port or range of ports to a single destination (IP address). In some cases, this may cause issues where multiple LAN
devices attempt to use a service simultaneously. Where possible, use an alternate port for any subsequent connections after the first device.
