With the firewall enabled in F-Secure Client Security 14 / Computer Protection, I am unable to reach the network share or printer


The default firewall rule blocks unknown inbound/outbound connections. Ensure that you have allowed the network traffic in the product firewall to port 135, 137-139 and 445. Whitelist the affected printer IP or port number to the firewall rule.

In case this does not help, we recommend to check the local firewall rules in the Windows Firewall user interface and ensure that there is no potential conflict between F-Secure firewall rules, and local firewall rules.
