Possiblities to build VPN's to connect different company LANs (Intranet VPN)

[Isabel Schmitt]

Hello everybody !

It's really difficult to get an overview about the different concepts of VPNs.
Who can tell me, if there is a general structuring of VPNs.
What are the different possiblities of Intranet-VPNs to connect different parts of a company.

Thanks in Advance
