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


Please Note: Once you have enabled IP Passthrough, the device that receives the public IP address will no longer be able to access the Hitron's user interface (described below). Likewise, as your Hitron will continue to operate its DHCP service, if you intend to use IP Passthrough for a third party router, it is recommended that you move all of your local connections (both wired and wireless) to the third party device.


To use IP Passthrough, you'll need to ensure that you have a second dynamic IP address available for your modem. 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 steps outlined below.

IP Passthrough can be set to the MAC address of a specific device on your network or by assigning the passthrough to a specific ethernet port on the back of your Hitron (possible ports: 1-4). Both options are described below and are setup via the web user interface for your Hitron modem.


1. Log into Hitron web user interface by addressing your web browser to and then entering the login credentials (default credentials shown):
