DIRECWAY Professional
FAQs
DIRECWAY Professional FAQs are relevant if you purchased the
Professional service plan.
1. Can I run DIRECWAY Professional on a virtual
private network (VPN)?
Running a VPN client over a satellite network is not an ideal
configuration. Although most VPN clients work, your speeds
may be affected significantly. While average download speeds are
slightly better than dial-up, they are reduced from typical
DIRECWAY speeds by as much as 50 to 75 percent. Average
upload speeds are comparable to dial-up performance. It is
recommended that those accessing secure information over a
VPN through DIRECWAY Professional do so on a limited basis.
To optimize your performance, disable your VPN client while
surfing the Internet, and enjoy the full speed of DIRECWAY.
When you need to access information from your corporate LAN,
you can enable your VPN client, keeping in mind that you may
see a reduction in throughput. At this time, Hughes Network
Systems, LLC (HNS) does not endorse or support any VPN
products. Customers that run VPN products do so at their own
risk and will not receive any support from Hughes Network
Systems, LLC (HNS) regarding troubleshooting, configuring,
optimizing, or maintaining a VPN connection.
2. Why does the service slow down when used in
conjunction with a VPN?
Our communication satellite is located over 22,000 miles from
Earth. Each data packet must be sent down separately and
acknowledged by the remote site. This process takes time. In
order to expedite the delivery of data packets to our end-users,
Hughes Network Systems, LLC (HNS) has developed a patented
technology for aggregating those packets and sending all of them
down simultaneously. VPNs encrypt each data packet, which
prevents our technology from aggregating the data packets and
reduces the throughput significantly.
3. What can I do to get DIRECWAY high-speed
performance if I want to connect to my company
network using a VPN client?
Hughes Network Systems offers a service enhancement called
DIRECWAY VPN Accelerator. DIRECWAY VPN Accelerator is
an enterprise network solution that can be purchased and
deployed by your corporate network or IT organization.
DIRECWAY VPN Accelerator provides a continuous high-speed
connection for VPN clients and does not interfere with
DIRECWAY’s performance enhancements. See
