What's a VPN? A Virtual Private Network. A misnomer really,
or more of an anacranism. In the old days if you strung two
T1 lines between two sites you had a Private network, or "PN".
Now days if you run a 'tunnel' or encapsulated link between two
sites it forms a 'virtual' T1 or Virtual Private Network.
Lots of people seem to be convinced that this is the next wave
of "remote access". To me it looks like a giant extension cord
from my house to the office. To my ISP it looks like more traffic.
To Microsoft it looks like a way to sell more NT servers. To the
VC's it's just another gamble. I wonder what the corporate IS guys
As the corporate firewall becomes a VPN server, more and more
Internet traffic will be via encrypted, authenticated tunnels.
Perhaps some day all Internet traffic will via virtual circuits
which are brought up and down on demand. Like phone calls,
only authenticated and encrypted. Sounds like ATM, huh? Don't
tell anyone I said that.
