Firewall Advice

[ACPCUP]

I am using Zonealarm which is a great Firewall but every now and then it stops me gaining acces to the net. I got to keep going in and allowing access. I have checked the box for allow without asking but can anyone say if i really need Zonealarm / Firewall or if there is a better (free) one available.

Thanks
