Are all VPN Clients compatible to all VPN servers ?

Can I use every (at least the most popular) VPN Client to connect to every VPN network ?
In other words is the VPN protocol standardized?

Or must the VPN Client fit to the VPN server ?

If client must fit to the server: How do I find out the server product name
(without asking the admin) ?

No, they are not all the same. Just within Microsoft you can use either PPTP
or L2TP depending on how the server is set up. There are also VPN clients
from Nortel, Cisco and others.

Don't even think about attaching to a network without informing the system
administrator. He'll need to provide you with credentials and the network
information.
 
Aloha Martin,

VPN isn't a protocol it's a technology. There are a number of different
protocols that do VPN, such as PPTP. Offhand I can't think of any way that
you could find out the server type without asking the administrator. Why
wouldn't you want to ask the administrator?

Click to expand...

And worse: Even though Nortel, Cisco, Checkpoint etc. all use the IPSEC
standard for their VPN implementations, it's often quite hard (and
sometimes downright impossible) to use an IPSEC-Client from Company A
to an IPSEC Router from company B :-)
