RFC 1483 via DHCP
IP Passthrough
IP Passthrough is a setting where your modem is handing off the usable static IP to another piece of equipment. This mode will also allow Windstream to support the Windstream equipment while allowing you to configure your own equipment as needed.
Note: While the Windstream equipment firewall will be protecting the Windstream equipment, you should make sure the device behind the Windstream equipment is also configured for your own security.
- Go to Advanced Setup, then select WAN IP Addressing
- Select RFC 1483 via DHCP
- Enable Unnumbered Mode. In the Gateway Address field set the first usable IP of the customer's static block along with the proper subnet mask. VIP mode is optional.
- If you still want to connect devices to the wifi from the T3200/T3260, when setting up IP Passthrough make sure to select the checkbox for VIP Mode (Private LAN subnet under step 4).
- Set DNS type to static and enter in Windstream's DNS IP's.
- Once these fields are set you can apply the settings. You must setup your router with one of the static IP's of your block. The gateway must be the IP address you set in our modem.
It is recommended to reboot the Windstream Equipment and any of your own equipment once the settings are in place.

The information entered for Gateway Address, Subnet Mask, Primary DNS, and Secondary DNS should be included in your Windstream Welcome Letter.
Once all the information is filled out, hit submit and you should be in IP Passthrough.
Depending on your overall set up, if you test your IP address online to see if it has worked, your modem may not show the correct IP address. If you filled out the information properly within the modem, then it is set up properly at the Windstream Equipment
Note: Anything using the Windstream Modem’s wireless may not be on the static IP. To use the static IP wirelessly, it is recommended to have a router connected to the Windstream Modem and have your devices connect to that wireless network instead.
