Title: o2/be with HG612
Post by: LeJimster on July 12, 2012, 03:19:41 PM
Hi all,
I've just got myself a HG612 which I then proceeded to unlock.  My thinking is since I'm getting VDSL2+ later in the year and I want to give my current router to a friend, I'd set up the HG612 on my ADSL line in the meantime.

The problem is it's not PPPoA and I'm not sure if the right settings are available to me?

First of all does it support "RFC1483 Bridge mode".  I can find various Bridged IP and PPPoE modes, but I don't believe they're what I'm after?

Any help would be kindly appreciated.  If its not possible I would rather be told now than later tho as I don't want to waste all day on a lost cause :).

Ta!

LJ

Update: I figured the settings out after much trial and error, they're posted further down.

Hi LeJimster & welcome to the Kitz forum.

Yes, an unlocked HG612 can indeed be used on an ADSL, ADSL2 or ADSL2+ connection.

A couple of members of this forum actively use the HG612 in just such a way.

I'm sure one of them will be along shortly to assist with relevant settings etc.
In the meantime, there is a little info here:-

http://forum.kitz.co.uk/index.php/topic,11404.msg220343.html#msg220343

These modes are available, with this example forcing ADSL2 mode:-

Modulations:
   G.Dmt   Disabled
   G.lite   Disabled
   T1.413   Disabled
   ADSL2   Enabled
   AnnexL   Disabled
   ADSL2+   Disabled
   AnnexM   Disabled
   VDSL2   Disabled

oh yes, sorry if I wasn't clear..

My ISP is o2 and we connect via a non-standard method.  Unfortunately I can't seem to find the right options on the HG612.  Either they're named something else or they don't exist.  If anyone on o2 has managed to get their line up and running with this hardware I would love to hear how they did it as I'm not the wiser for reading the manual.

Hmmm, best I seem able to do is to get it to Sync & obtain it's own IP DNS etc..  But I don't seem to be able to pass any data from LAN to WAN.

If you would be willing to tell me your e-mail address via a PM, I can send you a sequence of images that you could then consult.

Well I found the culprit, DNS!

Normally you can set your router's IP as the DNS server and it relays everything, but that's not working.  So I'll have to manually set it, not a big deal :).  Phew!

Glad you got it sorted LeJimster!   That's exactly what Burakkacat discovered: for some reason, the Huawei will only proxy DNS queries for its DHCP clients.  biohead of psidoc.com reported that he got the Huawei bridging with ADSL2+.  [1]  Not sure what type of bridge that was though, nor whether it was with o2/be.

cheers, a

I will list out what I did to get it working later, make some screenies prolly too.  It's not in any bridge mode, at least not what the HG612 calls a bridge mode, that was a red herring.  Anyway, hopefully somebody can fix the DNS problem in the future as I don't like always manually setting DNS, they have a habit of changing without notice :).

Here are my settings for o2 broadband ADSL2+ (LLU) on the Huawei Echolife HG612 / BT Openreach modem, they should work fine for BE* too.  They may not be perfect, but they should do the job :).  Note..  You can probably enable Both LAN1 & LAN2 on the WAN page, I personally don't need both ports.  Also, note if you are manually setting your IPv4 settings on each PC you will have to put in some working real world DNS IP's as you can't get away with pointing it at the routers IP :'(.

Hi biohead & welcome to the Kitz forum.

Not necessarily redundant.
It will still work just fine on your FTTC connection (even if you are connected to an ECI rather than a Huawei DSLAM).

At least you would be able to see & possibly graph your FTTC stats.

np Kitz.

I've been meaning to join the forum awhile.  I remember you from years ago on thinkbroadband forums as it was adslguide back then.  Been using your site for years for the guides when I forget stuff, it's been a great help.  So taking a few screenies is no big deal :).  I'm not expecting many people will be wanting to use it for ADSL2+ from o2, but who knows..  Maybe so when o2 finally get their ass into gear and offer FTTC.

As it happens, a project has just been started to set up a wiki page on the use of the HG612 on a Talk Talk connection, and your O2 information will be a valuable extension to that.
Title: Re: o2/be with HG612
Post by: biohead on July 14, 2012, 06:16:19 PM
What I found when using my HG612 on a Talktalk connection - man that thing was stable. I live on a longish line (3km+) and it wouldn't be unheard of for an ADSL modem to drop the connection through the night. It was very rare one would hold sync for two nights in a row.

I ran the 612 for a little under a month, and in that time I had 1 dropout. And I've a feeling that one dropout was a cause of me ordering the FTTC install as it occurred shortly after I ordered it.

Regarding my own fttc install, I will swap the ECI for my 612 at some point... it's just a bit too new to start doing that yet  :P
Title: Re: o2/be with HG612
Post by: LeJimster on July 14, 2012, 07:24:16 PM
The HG612 is very good indeed at keeping synced.  But it's no different to my ADSL2+ router that I had been using before.  I think the key is the Broadcom chipset and software..  They nailed it with the BCM6348 and since the HG612 uses a faster revision of the same chipset (BCM6368 i believe)..  It's kept all those great features.  I certainly wouldn't have bought it if it had something other than the Broadcom inside it.

Hello everyone  :)  I too have acquired and unlocked an HG612, primarily to keep a better eye on noise on my BE ADSL2+ line, before I move to Infinity2.
However, I seem to have another issue with DHCP in the box. My HG612 is configured exactly as per the screenshots shown on this thread.  However, it just won't issue an IP address from the pool, and I don't know why.  Monitored the direct connection with Wireshark: the laptop sends out the expected DHCP discoveries, but from the HG612 there is no answer, until it switches to APIPA, then the HG612 does reply.
What's (not) going on?  Can anybody point me in the right direction? (NB: tried different laptops too).
TIA

Hello Colin, welcome to the Kitz Forum.

I am using a HG612 as a two-port modem/router on my TalkTalk LLU'd line. I have just checked and DHCP is working correctly, for me.

With a statically assigned IP address.

With a dynamically assigned address.

Please take a look at the Huawei EchoLife HG612 Home Gateway (http://wiki.kitz.co.uk/index.php?title=Huawei_HG612) article in the Kitz Wiki. There you will see a succession of screenshots from my connection. As development of that article is currently ongoing, there are not that many words to be read . . .

On the subject of keeping in-sync, I can confirm that the HG612 has the tendency to "hang on". I have witnessed a SNRM of -1.9 on two separate occasions and it was only at -2 SNRM did the device finally "let go".  :)

I've just checked DHCP with the exact settings in the screenshot and I agree it works fine.  Have you got the device type set to computer on the LAN (DHCP Settings) page?  I don't know if that makes any difference having it set to other devices.

Another thing... If you are using a laptop I presume you are using wireless?  If thats the case, I would be looking at your access point and not the HG612.

Thanks B*K. LeJim, both for the welcome and the helpful advice.  I will go back (yet again) & recheck everything, but it's still bugging me for the moment.  To clarify, in case my poor description is misleading you all:
1) for these testing purposes, I am using a direct ethernet cable from the laptop nic to the HG612 Lan2 (or Lan1 for that matter). No wireless involved.
2) the ADSL2+ link Static IP works absolutely fine.  No DHCP involved on that side for me
3) it's just on the LAN client side that (at the moment) it won't assign an address from the pool.  Darned if I know why yet.
4) I don't want to admit it to myself, but I could swear it used to work (and of course I haven't changed anything :lol:), now it doesn't.  I have tried resetting it back to defaults and 'rebuilding' it, but obviously I must be making the same mistake.
Must try harder - will go back to the drawing board and report back.
Thank you all for making me feel welcome.
Colin

I should hope not. Otherwise you have a very rare and totally unique Huawei EchoLife HG612 Home Gateway!  ::)

If I am reading your clarification correctly, when your PC or laptop is connected to the HG612 using a statically assigned IP address all is well. When you attempt to connect your PC or laptop, configured as a DHCP client, to the HG612 (which is running as a DHCP server) the connection does not take place.

Assuming that you have the HG612 configured as shown on the LAN Settings page (http://wiki.kitz.co.uk/index.php?title=Basic#LAN_settings), then the problem must be with the configuration of your PC or laptop.

Perhaps if you go to sleep with that thought in you mind, when you next wake the solution might be "just there"?  :-\

There is a difference betweem LeJimster's DHCP settings and B*Cat's, though I don't know if it's relevant. In the middle of the DHCP server settings, the device type is set differently, and the IP address range below that line is set to 0.0.0.0 in B*cat's version.
Title: Re: o2/be with HG612
Post by: ColinS on July 18, 2012, 10:11:56 AM
Thanks to both B*K, and Roseway.
Roseway, I spotted that difference too, as well as some apparent differences in the makeup of the screenshots between the two (perhaps SP06 I don't know?). However, as per your hint, I have tried it both with a 'secondary pool' range for specific device types i.e. computer, and without.  For the moment it still seems deaf!
B*K: of course I am inclined to believe you are right, but a) I get the same effect with a different PC using a different version of the OS (which I won't mention) and b) using either PC, but a different router (in this case the TG784), its DHCP works.  So, it's certainly puzzling!
B*K, for comparison with your helpful info (BTW I have the HG612 v3B with the ASBOs SP10 firmware), here's mine:
br0       Link encap:Ethernet  HWaddr BC:76:70:B6:9F:11
          inet addr:192.168.1.1  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:6039 errors:0 dropped:0 overruns:0 frame:0
          TX packets:3647 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:750715 (733.1 KiB)  TX bytes:978758 (955.8 KiB)

eth0      Link encap:Ethernet  HWaddr BC:76:70:B6:9F:11
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:6049 errors:0 dropped:0 overruns:0 frame:0
          TX packets:3636 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:862893 (842.6 KiB)  TX bytes:1001500 (978.0 KiB)
          Interrupt:40 Base address:0x6a00

And that's even with the static IP address (actually 192.168.1.2) obviously or a) there would be no traffic, and b) I couldn't get this info!!!!
I will try to capture some screenshots and the Wireshark trace and post them, but before I do, let's see if I am doing something really obviously stupid and invalid in my tests:
I'm 'bench-testing' this (DHCP issue), so I haven't bothered to connect up the ADSL as I know that works and, well, ADSL has to be down sometimes and the modem still work!!
While I (hope) I have faithfully followed the given instructions, apart from unbinding LAN1 from the ptm I haven't 'deleted' any of the default VDSL stuff.  Is that necessary?!!
Thanks to all for their patience while I get myself sorted out on this. ;)
Title: Re: o2/be with HG612
Post by: ColinS on July 18, 2012, 01:06:36 PM
OK, thank you everyone.  I have it sorted now (at least for the moment).  On the principle of "what's the very least I need to do to make this work?", I:
1) reflashed the HG612 with Asbo's unlocked SP10 firmware
2) reset the configuration data in the modem todefaults
3) ticked enable on DHCP server on the Basic/LAN page
4) set my NIC to use DHCP
and voila, it works.
Now I'll carefully reintroduce the ADSL2+ EoIPoA data needed for Be, ad hopefully that's the end of this story.
Next steps are to put the TG784 configured as to use an Ethernet WAN in place of my laptop, and see if that works along the lines of the way BT's HH3 does.

Erm . . . If you are going to do that, then you do not want to configure the HG612 as a DHCP server,  :no:  you need to have it in bridged mode and use the TG784 as the DHCP server. A DHCP server after a DHCP server will put you in a double NAT situation.  :-X

It's also worth noting that previous attempts that merely reset the config to defaults did not, of itself, resolve the problem.  It did need the firmware to be reflashed too.   ???

I've successfully set up an HG612 as a router on my Zen/BT ADSL2+ connection. The DHCP server works when set up as shown in the wiki: http://wiki.kitz.co.uk/index.php?title=Basic#LAN_settings - and I agree with others that connected PCs pick up the DNS addresses when configured for DHCP, but not if the PC has a manually set IP address.

First reactions are that the performance is very similar to other Broadcom-based routers such as the D-Link DSL-2740B which I was using previously. But I'm uncertain about the firewall at present. Checking with Shields Up shows that most ports are closed but not stealthed, and I can't see a way to change that at the moment.

I have not yet finished adding words to the Wiki article but I did think it sensible to annotate the Frewall level (http://wiki.kitz.co.uk/index.php?title=Routing/Firewall#Firewall_level) and the following five images. Configured as those six images, Shields Up! (https://www.grc.com/x/ne.dll?bh0bkyd2) confirms that all ports are in stealth mode. Please see below.

I have the firewall disabled on the HG612.  And rely on my IPCop router sat behind it to do that role.  Although I'm a bit tardy with that too, got quite a few ports open that I haven't used for some time.  Should really disable what I'm not using.

pppd pty 'pppoe -I eth0' user anyone password mypass defaultroute replacedefaultroute usepeerdns

That works fine on TalkTalk LLU - and seems a little bit faster than with the Huawei supplying the ppp layer,  maybe.

Code: [Select]
May 12 20:22:46 l502x pppd[1388]: pppd 2.4.5 started by asbokid, uid 50
May 12 20:22:46 l502x pppd[1388]: Using interface ppp0
May 12 20:22:46 l502x pppd[1388]: Connect: ppp0 <--> /dev/pts/1

May 12 20:22:47 l502x pppd[1388]: CHAP authentication succeeded
May 12 20:22:47 l502x pppd[1388]: local  IP address 2.100.5.16
May 12 20:22:47 l502x pppd[1388]: remote IP address 2.100.0.1
May 12 20:22:47 l502x pppd[5303]: primary   DNS address 62.24.202.69
May 12 20:22:47 l502x pppd[5303]: secondary DNS address 62.24.139.9

The defaultroute and replacedefaultroute options of pppd cause the routing table to be modified automatically, and the ppp interface becomes the new default gateway:

Code: [Select]
# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         0.0.0.0         0.0.0.0         U     0      0        0 ppp0
2.100.0.1       0.0.0.0         255.255.255.255 UH    0      0        0 ppp0
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0

Code: [Select]
# ifconfig ppp0
ppp0      Link encap:Point-to-Point Protocol 
          inet addr:2.100.5.16  P-t-P:2.100.0.1  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1492  Metric:1
          RX packets:20600 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:3
          RX bytes:1754604 (1.6 MiB)  TX bytes:28989404 (27.6 MiB)

Ideally, the username and password should be tucked into the file /etc/ppp/chap-secrets (so that they aren't visible using 'ps', etc.)  But as TalkTalk LLU (and Openreach VDSL2) accept anything as a ppp/chap password, there aren't really any 'secrets' to worry about!
