VPN bogs down Internet connection

Networking Channel ATE — Wed, 20 Aug 2008 14:10:18 +0000

When the user connects through VPN, the speed the PC gets on the Internet from Comcast cable goes from 2 to 5 Mbytes to less than 100 Kbytes, per Toast.net

When the user tries to shut down their PC, it won’t shutdown, so they have to hold the start button down to turn it off.

I did notice that if the user disconnects the VPN, the PC connection to the Internet gets faster but not as good as before. Have you heard of this problem with Vista before?

Are network access control products finally living up to their billing?

Donnellymp — Wed, 09 Apr 2008 16:08:51 +0000

Network access control (NAC) products sound like a good idea. And they seem to work well to protect against inadvertent pollution by authorized users. But some experts think we should be skeptical that NAC products can fend off hostile attacks.

How to determine if a client-side Internet connection is using VPN?

Networking Channel ATE — Fri, 04 Apr 2008 19:42:33 +0000

A German Seti@Home user is asking the Boinc developers’ forum how one can determine if a TCP/IP connection is a VPN connection or not. Management of his company does not want Boinc using the connection if it is a VPN. Can you tell me how one can tell if a client-side Internet connection is a VPN using, presumably, the Windows API? Thank you in advance for your help.
