Mobile and DSL L2TP Handover: Overview

Our "data-only" SIMs allow for the possibility of L2TP hand over to your own LNS. (Note: our SIP2SIM SIMs don't have this ability - sorry)

Less common, but still possible, is relaying a DSL circuit to your own LNS, eg, an ADSL, VDSL, FTTP etc circuit.

This means that the data SIM (or DSL line) connects directly in to your network, and you control the IP address allocation, routing and any fire-walling or filtering as you wish.

The settings for a SIM can be set on the control pages. For DSL connections the L2TP settings are set by staff, so please do contact them for any changes or setup. The information that would be requested is:

Target IP (with an optional backup IP) - the L2TP server at your side
Host - the hostname we present
Secret - the password we use (optional)

SIM Configuration

Accessing This Feature

Access is via the Control Pages as follows:

Log in to the Control Pages with your xxx@a login
Click on the SIM ICCID you want to edit
Fill in the L2TP relay information there

You can enter the IP address of your LNS (and an alternative if you like), and a shared secret if you want to do tunnel authentication.

DSL Configuration

Wholesalers will usually already have their configuration set to relay based on their realm.
For individual circuits please contact staff to set up relaying on to your own L2TP server.

-L2TP establishes a tunnel, and over that tunnel it establishes one or
-more sessions, each of which uses PPP.
-The tunnel requires an endpoint address (e.g. l2tp.aa.net.uk or
-.155.53.19) and a hostname (which is sort of the login name for the
-tunnel). The tunnel can also include a secret, which we do not use for
-our L2TP outbound service to customer's L2TP servers.
-Once the tunnel is established, a session can be established over the
-tunnel. The session does not have to have any authentication, but it is
-normal for the endpoints to negotiate PAP or CHAP using LCP, and so the
-connecting end will need a username and password to complete the PPP
-level authentication.
-So, in total, you would need:
-#Tunnel IP
-#Tunnel Hostname
-#Tunnel Secret (if used)
-#Session Username
-#Session Password
-An L2TP session is PPP and can negotiate whatever authentication it
-likes for the session. In practice this is usually done by a proxy, so
-in the case of both SIMs and Broadband we will receive proxied
-negotiation details for the circuit, and will pass on those proxy
-details to the far end.
