At this year's Federal Security Conference, Microsoft announced that it
was dropping support for PPTP. I'm not really sure what this means when
it gets down to practice as Microsoft tends to support old technologies
that it foists upon the world.
I don't see everyone rushing out to purchase a new version of Windows just
to get L2TP which is Microsoft's replacement for PPTP. As Windows 2000
continues to slip, its a little difficult to determine when L2TP will be
available.
L2TP is interesting from a security perspective as it isolates the system
from its current network and connects it to the target network. Once the
connection is established to the target network, all connectivity is lost
to the local network, i.e. any mapped drives are unreachable as are any
shared devices such as printers. Voila! None of the back channel
problems of IPsec.
Avoids some of the problems that our corporate network group introduced
when they upgraded to Nortel's latest version of their VPN product. I
can't remember the products name, it was aquired with Bay Networks who
acquired it earlier.
