I just recently started taking a class at a university that has a completely open wireless network, so it is up to ZoneAlarm Pro to keep my laptop safe when I am on campus (at home I have my laptop behind ZAP and also behind a Natting router).

The problem is that I've been getting NetBios attacks from IPs from within the campus's network (i.e. -, assumably from some geeky college student in their dorm room, etc. who is also on the campus's completely insecure wireless network.

Shields-Up shows my port 500 (ISAKMP) as CLOSED (not stealthed) and port 264 (BGMP) as OPEN! I have the university's network placed in ZAP's Internet Zone (i.e., not Trusted), so why are these ports showing and how can I get ZAP to close them.
