Hi, I am using a BT Hub 2 as a main router. I would like to know if I can possibly plug a opnsense router into one of the Ethernet ports on the BT Hub and get it working like that without putting the BT Hub into bridge mode? I am from the UK if that helps.
Why are you wanting to do that?
For the additional ports?
If so, you want to use switches instead?
If for the additional wireless coverage, go for access points
