router behind another router

  • In my tests both THG3000's can authenticate to Vodafone if used separately, but can't when connected via the others LAN.

Does that imply if I'm with Vodafone I could connect two of these and both would connect successfully to the internet? Would that be both connecting to the phone line or one piggy backed into the other via Lan?


Absolutely not. It is apparently very unusual to be able to have 2 Vodafone routers working on one account.

The routers have to be "provisioned" to the account, but when I first joined I had a line fault which caused them to send me another router, but they couldn't get the new router to work at all even though they "provisioned" it.

Eventually after 3 months of hell they finally got Openreach to fix the fault. (I really wouldn't recommend joining Vodafone, the support is virtually non existent)

Later whist trying to help someone on this forum I connected the "spare" router to see what LEDs would be lit on an un-provisioned router and blow me, it worked, and as far as I know would still work but I'm back on the original at the moment.

It would never be possible to have 2 routers connected to a phone line together and the testing shows a second Vodafone router will not work behind another. (which is what we have been trying to achieve on this thread)

 

However, I have got a couple of Technicolor routers (same make as the THG3000) a TG589vac v2 and a DGA4231 (exactly the same hardware as the THG3000, but a different case).

They are both ex-ISP routers obtained from eBay but the firmware is original Technicolor and not too locked down.

I know the DGA4231 would do exactly what you want, as I was running it like that whist testing, but I had never even tried the TG589vac v2.

To cut a long story short, I configured it to get it's WAN IP address from the THG3000 and to run it's LAN on a different subnet (192.168.2.x) and it works fine, doing exactly what I think you want.

I'm typing this connected to it's wifi, I have the following connection stats:

Connection-specific DNS Suffix . : lan
Link-local IPv6 Address . . . . . : fe80::5112:d2d7:434b:44e1%4
IPv4 Address. . . . . . . . . . . : 192.168.2.177
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.2.1

Whilst the rest of my devices have 192.168.1.x addresses.

The only problem with the Technicolor routers is it's impossible to get firmware updates, Technicolor say it's up to the supplying ISP to provide them.

So you could possibly get a similar 2nd hand router, or If your interested in the TG589vac v2, PM me and we can work something out.

I would attach the TG589vac v2 specs and manual for you to peruse, but they seem to have removed the ability.

Edit: Added links.

Sounds like i need to find a way to flash the firmware from THG3000 to DGA4231

Good look with that. I can send you the firmware but I have not yet know anyone who has managed to flash the router

There is some information here

but it is not simple.

Cheers - in its current form it is of no benefit to me so I'm happy to tinker away!

 

Thanks for your help!

That would be ideal, but it's beyond my technical expertise.

This is the label  on the THG3000 board, so it's obviously a DRG4231 flashed with Vodafone firmware.

Mine is very similar!

I've also found what I believe to be the serial ports but outside of that I'm currently waiting for an update on

It would be great if they could find a way to flash it. They are not bad routers and so many must be being trashed. Criminal waste really.

I managed to find an old tp-link ap, which i've flashed openWRT on to, looks like this may be the way forward for me in terms of DHCP, and then use various old routers in lan <-> lan as the wifi access points over tagged vlans.
