The ip address
217.110.97.196
217.110.97.197
217.110.97.199
etc.
continously try to connect to our network, trying to open random ports: 64946, 64947, 57208, 54954 etc.
These ip adresses maintaned by some German F-secure company. Obviously we drop all these connections.
How can we stop F-secure trying to penetrate our network?!
