DIRECWAY Professional 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 will work, your speeds will be affected 
significantly. While average download speeds are slightly better than dial-up, 
they will be 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 via 
DIRECWAY Professional do so on a limited basis. To optimize your 
performance, simply 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 
will see a reduction in throughput. At this time, HUGHES 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 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 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.
