Hi Guys,
I must have read through every single post on here and could not get my new router configured correctly so in the end I went into the TalkTalk router admin and then into the Internet or WAN configuration page. When the page loads I clicked edit to bring up all the hidden fields that can't be seen when simply viewing the WAN connection!! Very important that you click edit to view the detailed information! This must be a U.I. design shortfall.
Anyway the important bits you need to get are:
TRANSFER MODE: VDSL WAN OR PTM
CONNECTION TYPE: IP ROUTING (PPP) or PPPoE
VLANID: 101
802.1p: 2
PPP INFO
PPP authentication mode: auto
PPP trigger mode:Always online
Now for the tricky bit. You need to find your username and password. I used the right click option in chrome and clicked inspect over the input fields to get the details.
The username on my router was:
autoconfig@talktalkbusiness.net
The password can be found in axactly the same way.
Put all these details into your new router and you will be connected! Without the NAT loopback issue if you got a good router
