Cool. If you want to keep your current landline number "just in case", then you can migrate it to Sipgate, which should trigger termination of the BT service.

There will be a one-off £30 charge and you'll probably need to stick £10 credit on it as well. There's no monthly charge for Sipgate Basic, and credit seems to last forever (I had an account that I hadn't used for about 5 years, and the credit was still there when I tried it again a few days ago)

It's also worth spending £6 on a copy of Acrobits Softphone to use with it, as that saves you buying any more hardware.

For these ONT terminated services, does the router need to do any auth or is that taken care of by the ONT?

Router needs to do PPPoE

Edit: And it uses CG-NAT unless you pay for a static IP. Not important for most but can catch you out if you're into self hosting.

Hi smouty.

Once the ONT has been activated by an engineer you can connect a router using DHCP to get online as our network uses IPoE rather than PPPoE.

All the best.

Would it be possible if a mod could tag this username as an ISP for the forum.

Thanks Chris.

So I think there is no issues with router single threaded performance like you find with PPPoE on BSD based routers?

We have a handful of users running pfsense - there were some initial problems with the way in which DHCP renewals were requested, but this has since been ironed out and I'm not aware of any performance issues.

ONT will handle any GPON/Layer 2 auth stuff - that is, “is this ONT authorised to connect to the PON?” - that’s a network operator function.

Higher level (Layer 3) auth (including IPoE and PPPoE although the latter is prob. more like Layer 2.5) is pretty much always handled by the router - an ISP/CP function.

Then you get some AltNets that combine the 2 into one unit - still really a router (with an ONT built-in or plugged in)

Thanks for that.
The upside is that the router can just route without the overhead of PPPoE encapsulation?
I think my APU2 may manage 400/400 if so but do have alternatives available.

Nope. If there is PPPoE on there - then it’s down to the router (or other directly connected device e.g. directly connected PC) to have a PPPoE client.

The ONT is oblivious to this - it’s job is to take GPON frames and convert them to Ethernet presentation. It doesn’t care about ISP authorisation like IPoE or PPPoE.
