Due to the high latency of 700 ms to 2000 ms, VPN tunnels via satellite connections are usually extremely slow. This is because the server waits for confirmation from the recipient that it has received all data packets.
If the server does not receive a confirmation, it stops sending data until it has received the confirmation.
Due to the delay of approx. 800 ms, the server always sends a bit, waits again, sends again and so on.
The data rate that is thus achieved is approx. 2-3 Mbit/s.
To solve this, we have the following solution:
We terminate the customer's VPN connection at our firewall in the data center and then establish encrypted connections via the satellite connection(s) to the remote peer.
From there, the connection is also encrypted, if required, to the customer's end device. This enables us to optimize the data traffic for transmission via satellite.
