Hello, I work in an office where we have a Symantec Firewall. There are several users with a laptop and a wireless connection through Airport.

The issue is that in the past days they seem to be out of internet connection (FireFox error that can't find the server and Entourage that can't connect to the account) but Airport is on and the green light is on at the Network Settings.

I just quit Entoruage and FireFox and everything goes back to normal. Is there a way that I don't have to do that all the time?
