ZoneAlarm Pro will protect the computer it is installed on automatically...there is no need (or option) to enter your IP address as to enable protection. Any attempts to hack your computer will be automatically blocked, and you'll receive a notification of such an attempt. Also, if an unknown program (a possible virus, trojan, etc) tries to connect to the internet, access anything "dangerous," or perform an "unusual" activity, you'll be notified as well and asked what to do (allow or block). However, ZoneAlarm will not protect your other computer, as it would connect directly to the internet (any data wouldn't pass through ZoneAlarm on your primary computer). Thus, I'd suggest purchasing a second license, or a multi-computer license, and installing ZoneAlarm Pro on both/all computers.
Hope this helps,
I was wondering if say I have dsl connected to the main PC and I want to connect another pc to my dsl router. How does zonealarm protect that computer?
does zonealarm just block hackers automatically without tellnig tell or do we have to type in the IP address in the zone alarm program for zonealarm to protect it?
