14.5 VPN
Functionality
For security modules that protect the internal network, VPN (Virtual Private Network) tunnels
provide a secure data connection through the non-secure external network.
The module uses the IPsec protocol (tunnel mode of IPsec) for tunneling.
In STEP 7 you can assign VPN groups to security modules. VPN tunnels are automatically
established between all modules of a VPN group. A module in one project can belong to
several different VPN groups at the same time in the process.
