I didn't think TR069 normally works in bridge mode? It doesn't on my ZyXEL VMG1312-B10A anyway. Have to take it out of bridge mode to let the ISP mess with it. I'm with A&A (in the UK) though and they don't massively care what you run your end.

It depends how they do TR069. My ISP has multiple interfaces, i.e. HSI (high speed internet, bridge or NAT PPPoE), Voice (bridge with ISP network, VoIP for phones), Voice_ATA (bridge with ISP network, VoIP via embedded ATA, modem acts as one IP phone), TR069 (through which CWMP communicates and also which exposes SSH, Telnet, HTTP and HTTPS management on an internal IP address, bridged with ISP network) and IPTV (used for IPTV STBs, bridged with their network).

All interfaces are separate, and if you bridge your modem it only bridges HSI on LAN1. Phone works, IPTV on LAN 2 and 3 works and of course TR069 works.

If on xDSL, ISP can see all stats on their end of the DSLAM, there is literally nothing to configure from the modem side, except maybe turn on/off certain modes, but by default they're all turned on.

The way the Zyxel box is configured in modem mode on A&A results in it not having a globally routable IP address, since your router gets it instead. I expect this is a common way to setup modem mode, and it feels like the "correct default" way to do it.

This makes basic connectivity between the Zyxel box acting as a modem and the TR069 server challenging, though perhaps not impossible (you could, say, allocate a small IPv6 prefix to the modem, but I'm not sure if A&A's TR069 servers work over an IPv6 only connection).
