Starlink is a satellite-based internet service and is initially provided without IPv6 and uses CGNAT for IPv4.
We have customers using our L2TP service over their Starlink, and the initial reports are that:
- Speed is good (especially compared to their slow DSL service)
- Latency is OK - about 40-50ms, but there are some latency spikes
- Slight packetloss
- Overall - worth it!
Here is a graph from an L2TP service:
