Configuring Kerio Control Firewall to Allow Kerio Connect Services

Overview

When you install Kerio Connect on a local network behind a firewall (Kerio Control), you must map the ports properly to send and receive communication over the network.

Note: The same ports should be opened for any other third-party firewall solution, like Sophos, Cisco, or pfSense.

 

 

Process

  1. In the Kerio Control administration interface, go to Configuration (gear icon).
  2. Select Traffic Rules.

  7. Next to the Service field, click Select.
