How can I open or redirect TCP or UDP ports on your routers?

To open or redirect TCP and UDP ports on the routers provided by us, follow this handy guide.

This procedure is meant for advanced users! Only manipulate these ports if you have a need for them. The incorrect usage of TCP and UDP ports can cause security breaches in your system. Do note that some troubleshooting solutions when it comes to connection problems require our agents to reset your router which can reset these configurations.

Please note that TCP/UDP ports 80 and 443 are exclusively reserved for Cogeco and must never be redirected or closed.

Before you begin, make note of the port numbers and protocols the service needs and reserve an IP for the local device.

Go to Settings and tap on Network
Scroll down and tap on the “IP reservations” button.
Select the device you want to apply the port forwarding rule to.
---------If you do not see any devices listed, reserve an IP for your device(s) first.
Enter in a Port name for the rule, External port, and Internal port numbers, and choose the Protocol, which in this case would be TCP or UDP
---------If you only need to open the port, use the same port number for the internal port as you did for the external port.
---------Using port ranges is not currently supported by the Home app. Individual rules are needed for each port you need to forward.Tap on “Add” to save the rule, which will be shown in the list of Port assignments for the device.
If you need to set more forwarding rules for that device, use the “Add a Port” button.
