The Bright Box 2 is a combined VDSL modem and wireless router supplied to customers of EE (Orange). It is manufactured by Arcadyan and uses a Broadcom bcm63xx SoC

These instructions are based on the latest firmware at the time of writing: v0.04.05.0001-OT (Fri Mar 24 17:29:32 2017)

Put it in bridge mode

• This is for if you want to use the Bright Box as a VDSL modem only, and have a separate router act as the PPPoE client (e.g. ubiquiti edgerouter), avoiding double NAT
• There is lot of nonsense, not least from people on EE's own forum, about how this cannot be done
• If desired, change the Bright Box IP and subnet before doing this because the settings tab becomes inaccessible
• Connect your router to port 4 (GigE) on your BB

Connecting to Cloudflare WARP with WireGuard

Cloudflare's WARP VPN uses a slightly modified version of the WireGuard protocol, but it remains backwards compatible with the normal WireGuard client software. This means you can connect to it on platforms which don't yet have an official WARP client, e.g. your computer or EdgeOS-based router.

Step 1

Generate a WireGuard keypair, as usual:

wg genkey | tee private.key | wg pubkey > public.key
