The following details are technical information for setting up a DSL router to make use of services on our ADSL lines (BT and TT).
(More info in your [[Information Pack]] (available from sales or via clueless if required).
= ADSL: Basic
{| class="wikitable"
! Setting || ||Description
|-
| Line type || Auto || Usually set this to automatic as it allows ADSL or ADSL2+ (depending on modem and line type).
|-
| Mode || Routed || This means that IP traffic is routed, and is the normal mode unless setting up a PPPoE bridge to another device.
|-
| PPP mode || PPPoA || When routing IP you want your router to connect using PPPoA mode. PPPoE (see below) is more commonly used when bridging to a separate PPPoE device such as a FireBrick
|-
| VPI/VCI || 0/38 || This is often the default on most broadband routers
|-
| Mux || VC-Mux || This is often the default on most broadband routers
|-
| Login || As advised || We allocate a login for one or more lines. This is of the form of a name followed by @, a realm, a dot then a single digit number. (e.g. test@a.1). The final number is the line number (e.g. 1, 2, etc.) for where customers have multiple lines sharing IP addresses.
|-
| Password || As advised || We allocate a password, but you can change this on the Broadband Control Pages. If you change the password on our system your lines will go off line until you change the password on the router as well. If your router cannot handle the length of password we provide, please contact support who will be happy to set a shorter password.
|-
| WAN IP (local) || 0.0.0.0 || Whilst we allocate a fixed IP address for your service, including the WAN address, it is best not to set this as it is allocated automatically using PPP. If you configure this incorrectly you will normally find you cannot log in at all.
|-
| WAN IP (remote) || 0.0.0.0 || The IP address for our end of the PPP link should not be configured. This is allocated by PPP automatically. This will change depending on equipment at our end and may even change on every connection in the future.
|-
| LAN IP || As advised || If using NAT then this will be some default such as 192.168.1.254. If you have a block of IPs from us, use the IP and netmask as advised. DO NOT make up a netmask for use with a real IP address that we have allocated - always use the one we have advised.
|-
| Routes || As necessary || If you have a separate router/firewall link block, you will need to configure a static route for your main IP block via your router/firewall. You may want your DSL router to act as a DHCP server for your LAN.
|}
==Note==
Please note that most DSL lines (BT and TT) do allow PPPoE mode. This can be useful when using a bridging modem. In such cases you need the LLC-Mux normally. For FTTC and FTTP the only operational mode is PPPoE directly with RFC4638 support allowing 1500 byte MTU.
=VDSL=
{| class="wikitable"
! Setting || ||Description
|-
| VLAN || 101 || (Not applicable if you are using the Openreach modem). Use this if your router has a built in VDSL modem.
|-
| Login || As advised || We allocate a login for one or more lines. This is of the form of a name followed by @, a realm, a dot then a single digit number. (e.g. test@a.1). The final number is the line number (e.g. 1, 2, etc.) for where customers have multiple lines sharing IP addresses.

=DNS Revolvers=
Your PC/router will normally be configured to obtain an IP address and DNS servers automatically, and so not need any special set up. This will depend on how you set up your network and your DSL router.
==IPv4==
*217.169.20.20
*217.169.20.21
These are provided to your router via PPP, and some routers will provide a DNS relay feature allowing you to use your local router LAN IP address as a DNS service. If configuring manually please use these two addresses as our main customer facing DNS resolvers.
==IPv6==
*2001:8b0::2020
*2001:8b0::2021
These are our customer facing DNS resolvers for IPv6 use. The DNS servers can be obtained by your router using DHCPv6 over PPP.
