Overview

We can use L2TP for various things! For example:

• AAISP Data SIMs can be relayed on to your L2TP server
• AAISP DSL lines can be relayed on to your L2TP server
• You can connect in to AAISP over an L2TP tunnel from a non-AAISP internet connection

Our own FireBrick devices can be used as an LNS or L2TP client - from single sites up to full gigabit LNS capabilities.

Incoming L2TP

This is used to connect in to AAISP over a third-party internet connection. This gives you your usual AAISP IP (4 and 6) blocks and access to the internet as if you were conencted via a normal DSL circuit.

L2TP Handover/Relay

This relays in a data connection from a mobile SIM or a DSL line to your own L2TP server. This enables you to manage the IP addressing, connectivity yourself.

L2TP from Customers to AAISP

This is used to connect in to AAISP over a third-party internet connection. This gives you your usual AAISP IP (4 and 6) blocks and access to the internet as if you were conencted via a normal DSL circuit.
