FTTC install - Huawei modem - IP address clash etc?


[link to this post]
 
I've ordered an 80/20 FTTC install for early June (ISP = Goscomb). I have been doing some thinking in advance and have four questions I've love to have some insight on.

I'm OK with most aspects of home networking and would certainly like to unlock and monitor the Openreach modem if possible. I intend to offer up the modem to the EWAN port on my existing Billion 7800n, which currently has a local IPv4 address of 192.168.1.1

These are my questions:

1) I have obtained instructions and firmware for reflashing the HG612. Is it as simple as it appears? Aren't there any Openreach settings which I don't know and can't retain during the firmware upgrade? Does the modem 'just work' again after unlocking?

2) I intend to give the FTTC a week (10 days?) to settle once installed before looking at accessing the modem. Will I have any problems with IP conflicts? I see the HG612 has a default address of 192.168.1.1, and I have already assigned that to my existing ADSL router (Billion 7800n). Will I need to change the address of the Billion, even if I don't access the modem?

3) I realise I may get the ECI modem rather than the Huawei, depending on the cabinet equipment. Is there any way to tell in advance which modem I might get?

4) Does the HG612 'do' IPv6?

Thanks for any responses!

Yes - it is as easy as the instructions say! Dont even need to have it connected to the VDSL line. The only pre-requisite is that the computer accessing the LAN port MUST be 192.168.1.100. The BT defaults are retained.

I am not sure about changing the IP address of the Huwae but the GUI is such that it is probably possible.

It seems to be luck of the draw which you get although it seems that the selection, in theory, depends on the make of the CAB but either will work. I obtained a brand new Huwaei version 3b off ebay while waiting for my exchange to be enabled.

The Huwaei is acting as a modem - it is the router that would have to do IPv6 but the ISP would have to as well.

OK, many thanks for replying.

I already connect with IPv6 using my existing ISP and router.

I'd already looked on ebay for a modem to play with. Nothing much available at the moment, unfortunately.

You can find the answer to that question by locating the PCP through which your line is connected and examining its FTTC twin.

If you are still uncertain, take a photograph of the FTTC and post a link to the image here. One of us should then be able to identify it as either Huawei or ECI. wink

OK good stuff I will have a look at the new cab in the morning. I know exactly which PCP and where.

Absolute total RUBBISH.


If you are going to make statements like that then make sure they are correct rather than trying to mislead people.


And yes I do know what I am talking about, my local IP is nothing like that and I can access my Huawei modem without any problems whatsoever.

Correct, as long as the PC is set up with an IP in the 192.168.1.x you can access the 192.168.1.1 modem IP to unlock. Don't know why MHC states it must be .100 ?

Basically ignore your Billion to start with. plug direct in to LAN port 2 on the Openreach modem and follow the unlock procedures. Then access the modem at 192.168.1.1, go in to LAN settings and change the IP to something like 192.168.1.250

Then, plug a cable between LAN 1 on the modem to your WAN port on the Billion and have the Billion connect using PPPoE, and also plug a cable in between LAN 2 on the modem to any LAN port on the Billion (or a switch) and then you can access the modem on 192.168.1.250 and it wont affect your Billion at 192.168.1.1

Thanks

Just to add agreement there James.

I did follow the asbokid instructions originally, but thought the .100 was probably just a way of trying to avoid any conflicts anywhere.

For a bit of fun when deciding to revert to my Buffalo router, which defaults to 192.168.11.1, I now have the Huawei modem set to 192.168.11.101. (Rather than changing the Buffalo address).

The modem is accessed wired from the machine that was used to unlock it, and wirelessly from this machine.

Also, as you know but the others reading may not, once unlocked it is perfectly possible to use it as a 2-port router. No wireless of course.

Does this mean if your router defaults to an IP of 192.168.1.1 you are better changing it before getting fibre? i.e. either the BT provided modems have an IP of 192.168.1.1 so your router and its DHCP range must not include 192.168.1.1?

TIA
