Moved house, and stayed with TT. Got a new modem (DSL-3782). I'd like to put it in bridge mode, so the WAN IP passess through to my own router (OpenWRT based). On the old router I had (tiny one, only 2 Ethernet ports), this was possible-but I think with this one, its not? If this is right, could someone recommend a decent DSL router I could do this with (I suppose I could use the old one-but the username/password seemed to be hidden on this new one, so if someone could point me on how to get that username/password, I can try it on the old one 🙂 )
Cheers in advance
If you want to put the 3782 into bridge mode and connect it directly to the line nothing will ever have access to the internet. Bridge mode disables all of its routing functions, there for no traffic will be able to route to the router''s public IP address, which is a totally different network.
What you really mean is to configure the 3782 into modem mode. The 3782 does not natively support modem mode. However, I have seen a thread where someone did manage this. I will try & find it for you.
I gave up and took the old router-that seems to support "pure" modem mode. Set up PPPoE on it with my username and password, public IP now "sits' on my OpenWRT router. However, the line stats dont look as good on it as the newer one, so I may be looking on fleabay for a VDSL router that is good at *just* being a modem, so i can hand off all routing and wireless functions to my OpenWRT/LEDE router. Any recommendations?
I think I have seen the thread about the 3782 working in modem mode-I tried that, with no joy-I could not lease a public IP, trying both PPPoA and PPPoE
Anither approach is to leave the 3782 in default config and connect it to your other router via Ethernet & put that router in bridge mode and disable it's DHCP server. You can then disable the WiFi on the 3782 if you want.
I have found the configuration that apparently does work as Modem Mode (despite the first screenshot putting in Bridge mode). This was on a fibre connection.
This does apparently push the public IP address directly to the second router. The user who told me about this was @charlesb224.
This method does work. I used it whilst I was inbetween modems and needed to have the WAN IP assigned to my router.
I've successfully put the following routers into modem mode:
the KEY element is to ensure you disable the DHCP server on the Talktalk device, otherwise it will provide a NAT address to your router. When you disable DHCP server, the DHCP request hits the WAN via the 'bridge' and the Talktalk WAN DHCP server assigns the address to your router.
Hi cabbers, as the others have said it should work. Have you got another router you can test with just to make sure it's not your openwrt based one?
I think I responded further up on this-but I put in my old TT DSL router (small D-LINK) and set up the OpenWRT router to PPPOE, stuck in my username and password-and it works! Not sure if putting in the newer TT router would massively improve things-but the current set-up works, so I'm not touching it. Besides, HyperOptic are just about to start selling in here, so I'll be off/not renewing my contract 🙂 Who-hoo!!
Are you on Fibre or ADSL? If Fibre, are you on Business or Residential?
If the answer is Fibre/Residential, then you don't need to use PPPoE, the only requirement is to set your OpenWRT router to Dynamic IP/DHCP to connect to the service if you've configured your TT router as above.
Works for me as just setup with a Asus 86U Router
I have followed all the steps above (the screenshots), connected my Asus DSL-AC68U to the DSL-3782 via a cable, connected a PC to the wifi of the Asus, but then I couldn't manage to open the webpage to configure the Asus. How did you access and configure the router?
192.168.1.1 opens up the TalkTalk configuration
http://router.asus.com doesn't work
I went to the TalkTalk router configuration page, home, connected clients, tried the IPs of the other clients, but the Asus router wasn't there
For reference, just in case it might be helpful to others:
I switched off the Talktalk router. Connected a laptop to the Asus via network cable. Set the Asus to router only as described here: https://www.asus.com/my/support/FAQ/1016292/
Then switched off the Asus, connected to the TalkTalk router via a network cable, followed the steps in the screenshots a few posts above, switched off wifi on the TalkTalk router.
Finally, I connected the TT and the Asus via cable - note the cable must go in the specific port specified when setting up the Asus as router only.
It all worked fine, except there was no internal DNS: \\mynas no longer found the NAS, but connecting to the specific IP address of the NAS worked. Most home users do not have a NAS or similar device whose name needs to be resolved, so they wouldn't even notice.
I followed the steps described here:
to set the internal DNS (LAN on the left bar of the Asus menu -> DHCP and DNS on the right) to the IP of the router (in my case, 192.168.1.1) and it all worked fine.
Oh, I also set the WAN DNS to Google's , so Talk Talk can no longer hijack the page if an address is wrong.
