The output of a modem is serial, the output of this device is ethernet.

Actually, as modem stands for modulator-demodulator, it applies to conversion to/from discrete multitone modulation (DMT, as used in ADSL, VDSL, etc) just as well as it applies to a modem sitting between a serial line and a telephone line, or in fact anything else which can be used'to carry digital signals over an analogue line.
So the use of modem is correct, even though it isn't an old 110 baud thing sitting next to a teletype.

It's a Home Gateway - that's what the HG in HG612 stands for.

That doesn't stop it containing a modem... in fact, if it didn't it would not work.
And what defines a modem is not serial or otherwise, but the conversion between analogue and digital signals.

I can't see any reason to think of the device as a modem, it's like thinking of a car as an air filter.

You are arguing that it cannot because it is a car.

Thanks.

I had a play and I managed (eventually) to get the Billion in bridge mode and the WAN i/f on Pfsense setup as PPPoE late last night. I setup the /30 on the LAN side and as a VIP on Pfsense to be able to still access the Billion for SNMP purposes (I run MRTG to log various data) but I was unable to get it working.

It wasn't until I reverted everything back that I realised the routes back the to /27 and /29 were missing so that was the probable cause.

I think I'll change it back over tonight and run it for a while - I think the chances are I'll just stick with what I have. I've been running Pfsense for a number of years and it's never let me down and I have a dedicated hardware box for it now so I might as well stick with it.

You are welcome, and any questions somebody here will know the answer.
I guess your Billion router will still need a route back to the IP address you run MRTG from, if that was the problem.
BTW, you won't be able to collect the same type of stats from the OpenReach modem unless you unlock it.

In reply to a post by pete_thomson:
This post comes to you over a connection using pfSense 2.0.2 and a BT Huawei HG612 modem, though I'm using Zen, not AAISP. pfSense is terminating the PPPoE.

The only snag with this setup is that pfSense doesn't currently support RFC 4638, so you're limited to a WAN MTU of 1492 bytes. I'm looking at adding the necessary support and have scoped out the work to be done, but have no timescale for it. Unfortunately, it seems likely to need two patches - one to the mpd PPP daemon and one to the FreeBSD kernel (as the majority of the work for PPPoE is done using the netgraph system in the kernel).


Sorry to hijack a little but do you have the reconnection bug, where if the HG612 power cycles, pfsense doesn't connect back up automatically?

Yeah - When I switched from PPPoA to PPPoE to dropped the 2 routes from the config so I'm guessing that what was wrong.

I was aware that you could unlock the OR Modem but that will have to be physically a second connection - I have 2 spare NICs on my Pfsense box so I might just activate one of those and run a cable back to the modem.
