how can I add my network station (Lacie2) to F -Secure Client Security?
Everytime I want to access the station I have to shut down F-Secure.... Not very safe.
You're in Home Security and not Business Security.
Anyway, If I remember correctly you need to add a firewall rule to allow traffic to and from the IP of your Lacie2 and select services/protocol. If you don't know all protocols to allow then allow all traffic to and from that IP.
This will help you more:
