Unifi and BT Broadband

[MehulLakhani]

Hi All

Just looking to upgrade my internet at home.We have a BT Broadband and the normal router on a 80mb FTTC product.

Want to move over to Unifi, which I know fairly well.

I guess I cant replace the BT Broadband hub, as it still takes a normal telephone line connection.

I have a spare UCG Ultra. I want to connect this to the BT Broadband hub. What do I need to run of in the settings etc, so that only one thing gives Ip addresses ? Disable NAT ? Is double NAT a problem ?

Any help appreciated

The BT broadband hub acts as a modem and router. You can take it out of the equation (and totally avoid double NAT) if you find a dedicated modem set to passthrough mode. So the setup would look like:

Faceplate -Telephone cable here-> Dedicated modem -Ethernet cable here to WAN port->UCG Ultra

Barebones approach would be something like a HG612 but they are pretty old now. Some others also go for Draytek Vigor (numerous models). I had success with a Billion 8800NL.

Another idea would be to look for a BT Business Smart Hub 2 as that has the ability to also act as a dumb modem: https://business.bt.com/help/article/how-do-i-enable-bridge-mode-on-my-bt-business-smart-hub-2/ (why they didn't put this on the normal router hidden behind some special pages is beyond me).
