Learn how to use IP passthrough for using your own router or firewall with SmartWiFi.

When to use existing equipment

IP passthrough will split your routing equipment from the main SmartWiFi network and is generally used for secondary networks, rather than the primary office networks. If you operate multiple networks, setting up IP Pass through will work if your business runs separated or multiple networks for uses like:

  • Email/web/data servers.
  • Security appliances.
  • Multiple separate networks.

If you only have one router but have customized routing settings, the SmartWiFi modem can actually fully replace most singular network router needs. See How to mange SmartWifi router settings for more info on using the SmartWiFi to replace your existing router.


What to look out for

Any private network outside of the main SmartWiFi network will prevent automatic shared resources between the two networks. These shared resources might include:

  • Networking printers, scanners and copiers.
  • Shared network drives.

Often this is the intention of a separated private network, and there’s ways to get shared resources to work across multiple networks if needed. This is just a common forgotten point when setting up an IP passthrough network.

Multiple private networks will require subscribing to multiple static IPs. Check the static IP configuration email received from Shaw. If you need more static IPs, contact sales, billing or technical support to verify the account and request additional static IPs.


IP passthrough setup basics

IP count:
Each plan includes one static IP, with additional static IPs being available for additional cost, with up to a maximum of 8 total IPs available per plan. Make sure to subscribe to enough IPs for the setup you’ll need.

Modem port use:
Your SmartWiFi Hitron modem has 4 Ethernet ports, but only use the 4th(bottom) port for IP passthrough devices. Using Ports 1-3 can cause connectivity issues and should be avoided. Use a quality Gigabit Ethernet switch if you need to use multiple passthrough devices.

Mixed SmartWiFi LAN & IP Passthrough:
Using the SmartWiFi network for some Ethernet devices, while also using private networks with IP Passthrough is supported. Clearly marked Ethernet cords, preferably colour coded cords, and careful documentation should be maintained. Shaw agents will not know which devices need to be used which way and cannot support your internal 3rd party equipment. The preferred configuration this type of network: MAC Based IP Passthrough.

  1. Hook up all equipment into a single gigabit switch hooked into Port 4 of the Hitron modem.
  2. Use MAC Based IP Passthrough method, adding MAC address of each passthrough device into Hitron modem setup.

MAC Based IP Passthrough

MAC based IP Passthrough allows specified devices to bypass the internal DHCP and obtain an external public IP address based on the device's MAC address.

Note: Remember that if you change out your equipment it will have a new MAC address which will need to be updated on the Hitron settings.

  1. Connect a computer direct to Hitron modem.
  2. In a browser window, login to the Hitron settings (default: 192.168.0.1).
  3. Login to Hitron settings (usually 'cusadmin' and passphrase listed on modem).
  4. Go to 'Admin' menu at top, then 'IP Passthrough'.
  5. Set 'IP Passthrough Enable' to 'ON'.
  6. Set 'IP passthrough Mode' to 'MAC'.
  7. For 'IP Passthrough MAC' field, enter your router's WAN interface MAC address, then click '+' icon to add it.

  8. Verify newly added MAC address shows below '+' symbol to verify it's being added.
  9. Click 'Save Changes'.
  10. The Hitron modem will reboot. Services will be restored once the '@' symbol is lit up solid.
  11. Any static IP info will need to be manually programmed into your 3rd party equipment.
  12. Document your settings for future reference in case the settings need to be re-entered.

Wiring Notes

  • Use a gigabit switch connected to Hitron's port 4 to allow wired devices to be connected to the main SmartWiFi's private network. Connect the IP passthrough router into the switch as well.
  • For multiple passthrough networks:
    • Make sure you subscribe to enough additional static IPs with your SmartWiFi plan.
    • Repeat step 7 to add multiple MAC addresses.

    Port Based IP Passthrough

    Port base IP Passthrough allows the specified port on the Hitron to bypass the internal DHCP and allow any device connected to the specific port to receive an external public IP.

    1. Connect a computer direct to Hitron modem.
    2. In a browser window, go to Hitron settings address (default is 192.168.0.1).
    3. Login to Hitron settings (usually 'cusadmin' and passphrase listed on modem).
    4. Go to 'Admin' menu at top, then 'IP Passthrough'.
    5. Set 'IP Passthrough Enable' to 'ON'.
    6. Set 'IP passthrough Mode' to 'Port'.
    7. For 'IP Passthrough Port', select '4'.
      • Only port 4 should be used as ports 1-3 are reserved for Shaw equipment.

    8. Click 'Save Changes'.
    9. The Hitron modem will reboot. Services will be restored once the '@' symbol is lit up solid.
    10. Any static IP info will need to be manually programmed into your 3rd party equipment.
    11. Document your settings for future reference in case the settings need to be re-entered.

    Wiring Notes

    • For multiple passthrough networks, use a gigabit switch connected to Port 4 and make sure you subscribe to enough additional static IPs with your SmartWiFi plan.
    • Any device plugged into passthrough port will get it's own unique public address and can't be used for the SmartWiFi's private LAN.

    Shaw Support Scope

    Shaw phone agents can help make sure you’re able to sign in to the SmartWiFi modem to make the changes needed to our equipment, and direct through the basics of the IP passthrough feature. All modified settings are best saved and recorded separately for safe keeping. This will prevent loss if something should happen to the SmartWiFi modem. Shaw does not provide on-site IT support and cannot help in the setup, maintenance or troubleshooting of 3rd party networking equipment.
