= Using the AAISP L2TP service to get public IPv4 and public IPv6 addresses over a Starlink connection =
Starlink is a satellite-based internet service and is initially provided without IPv6 and uses CGNAT for IPv4.▼
== Overview: ==
'''The L2TP service''' from AAISP can will route a small block of public IPv4 address and IPv6 addresses to your (L2TP compatible) router. This gives you the ability to use pubic IP addresses that are not filtered, not behind Carrier Grade NAT or any sort of NAT. All you need us a router capable of L2TP and an [https://www.aa.net.uk/broadband/l2tp-service/ L2TP service from AAISP].

== In use: ==
We have customers using our L2TP service over their Starlink, and the initial reports are that:
* Latency is OK - about 40-50ms, but there are some latency spikes (shown as green on the graph below)
* Slight packetloss (shown as red on the graph below)
* They enjoy the public IPv4 and IPv6 from us
* Overall - worth it!
Our L2TP service enables the Starlink customer to have static, public, IPv4 and IPv6 addresses.

We monitor our connections with a graph that that measures packet loss and latency. Here is a graph from an L2TP service:

Note: This feedback based a very small number of connections (2 as of April 2021!), so the service may vary/improve depending on location and as Starlink add more satellites.
== How to use it ==
In short, you'd need to purchase and configure a router that is capable of L2TP and use that as your gateway. There are many routers which have this capability. You can just use the L2TP features built in to your computer's operating system (eg Windows/Mac/Linux) and test that it works before buying a new router. There are various setup guides on [[:Category:Incoming_L2TP]]
