Configuring a tunnel connection 
A VPN tunnel for secure communication can only be established if the SCALANCE M-800 
and the CP are assigned to the same VPN group.

command "Insert" > "Group". The group is automatically given the name "Group1".

3.  Select the SCALANCE M-800 and the CP in the content area. Drag the modules to 
"Group1". Both modules are now assigned to "Group1". 
4.  Change to advanced mode with the menu command "View" > "Advanced mode".
