hey all this is more of an opinion type of question i would say, but here it is,
i have been having trouble with a person(s) attempting to hack onto my private network. i believe that it is one persistant person because they continue to target a specific port from different locations, but he is very good at spoofing his IP to the point that it is random and to me untraceable. i already run ZoneAlarm, & BlackICE. but i just want to know is there more that i can do to protect myself. or is there some specific firewall that is very good at stopping port scans or attempts of?
