IP Passthrough allows you to assign a public IP address to a device connected to your Arris modem. Whether you're looking to use a third-party router or troubleshoot possible connectivity issues, IP Passthrough bypasses your Arris modem's internal routing.

About IP Passthrough

To use IP Passthrough, you'll need to ensure that you have a second dynamic IP address available for your modem. The automatic availability of multiple dynamic addresses is dependent upon your Internet service package. Once you have enabled IP Passthrough, the device that receives the public IP address will no longer be able to access the Arris user interface (as described below). Please contact customer support to confirm or arrange for your free IP address: Shaw.ca/ContactUs. Once you have confirmed the availability of a second IP address, please follow the setup steps outlined below.

While we have provided the following support information, we want to ensure that our customers receive the best possible support for their third-party hardware and software by speaking with the experts. The best way to resolve your third-party issue is to use support resources from the original manufacturer or developer. If the following information does not answer your question, please visit Arris Support.

How to enable IP Passthrough

Did you know? Slow Internet speeds, especially through a WiFi connection, can sometimes be resolved by resetting your Shaw Internet modem. To do this, locate the Internet modem in your home and unplug it from power for 30 seconds and then reconnect it. After a few minutes, your Internet connection will be restored and you can check and re-test your internet speeds at speedtest.shaw.ca to confirm the solution.
