VPN: Virtual Private Network; logical connections (so-called tunnels) are es-
tablished via existing unsafe connections. The end points of these con-
nections (tunnel ends) and the devices behind can be considered as an
independent logical network. A very high degree of tap- and tamper-
resistance can be achieved with the encryption of the data transmis-
sion via the tunnels and the previous two-way authentication of the
partcipants at this logical network.
WAN: Wide Area Network; a network consisting of computers, which are lo-
cated far away from each other.
WAN group: Defines a collection of WAN interfaces that can be started or
stopped in parallel.
WAN interface: An interface that serves to connect the local network (or one of
the local networks) with a superordinate network.
WAN chain: Defines a WAN by arranging WAN interfaces or WAN groups in a se-
quence.
