Using a VPN with HughesNet

Running a VPN client over satellite is not an ideal configuration. If you choose to run VPN over satellite, your data speeds may be reduced by as much as 50-75%. You can restore your connection to full speed by simply disabling your VPN client when your session is over.

Why does the service slow down when used in conjunction with a VPN?
HughesNetuses sophisticated acceleration techniques to enable high-speed performance over satellite. These acceleration techniques require access to data packet header information, which is blocked when IPSec-based VPNs are used. These VPNs encrypt the data and create a secure tunnel through the HughesNet network. The encrypted data cannot be processed by HughesNet's acceleration techniques, therefore resulting in slower performance.

Transmission Latency
Transmission Latency refers to the amount of time it takes a packet of data to travel across a network. With satellite service, that data must travel up to the satellite and back (about 45,000 miles). This round trip adds about a half-second delay to the total time your computer takes to communicate with a Website or host server. Therefore, time-sensitive applications that require fractions-of-a-second user inputs (such as multi-player "twitch" games or real-time equities trading) are not recommended with HughesNet.

Note: HughesNet Technical Support does not provide help with configuring or troubleshooting problems associated with VPN clients. For questions about your VPN product, please contact the manufacturer's tech support. SSL-based VPN products have proven to work more efficiently over satellite than IPSEC-Based VPN products. For questions or recommendations on a VPN product that will work more effectively with your HughesNet system, please contact one of our Satellite Internet Specialists.
