VPN and Satellite Internet were just not designed to work together.
Satellites in a geosynchronous (GEO) earth orbit maintain their positions at about 22,400 miles above the earth. Even at speeds approaching the speed of light, there is a propogation delay (measured in milliseconds) as data travels up to the satellite and back down to earth. These unavoidable end-to-end delays range from between 550ms-650ms for the iDirect based Mobilsat Enterprise ISP network, and 700ms-900ms for the HughesNet network.
This higher-than-expected latency inherent in geo-synchronous satellite connections presents a significant obstacle to virtual private network (VPN) connections over satellite.
The most common type of VPN is an IPSec VPN , either 3DES or AES. Unfortunately, IPSec VPNs have the most problems when used over satellite. Running an IPSec VPN over a satellite connection will result in a loss of 40% to 70% of the available throughput of the connection. Many of today’s latency sensitive applications fail in a satellite VPN enviornment for this reason.
