BT Hub 3\. Hardware upgrade. DHCP on WAN fails.
-
I recently upgraded the hardware of my pfSense to a new 64 bit system. The system has two WANs, a BT FTTP using a BT Hub 5, and an ADSL for failover using a BT Hub 3. On the new hardware, I spoofed the WANs' MAC addresses to match the old system. When commissioning the new system, the fibre WAN worked seamlessly. However, the ADSL WAN could not get a DHCP IP address from the BT Hub 3. Anyway, short story, in System -> Advanced -> Networking tick the box 'Disable hardware checksum offload'. All fixed.

N.B.
1) The BT Hub 3 worked with re3 but not re0. Notice that they're different chips. re2-4 are on a daughter card. BT Hub5 was on re4. Also, re0 worked fine as a LAN.
2) I have an apparently identical system in another location that works fine where the BT Hub5 is re0, and the BT Hub3 is re1. Go figure.
Hope this helps someone. -
I would recommend switching to real modem devices rather than using the HomeHubs as a modem if you can. Or at least quasi real like the HG612 ;)
