Firewall Configuration
For the data transmission of CP-Link 3 participants over the network, some firewall rules have to be configured for an
active firewall in order to allow the CP-Link 3 participants to communicate through the firewall. The setup program for the
CP-Link 3 Software configures these firewall rules during installation.
The following table shows the firewall rules for CP-Link 3 Clients:
