Firewall or not ...

[Kiffin Gish]

I have installed FreeBSD 5.4 on my Dell Inspiron 8200 using WiFi to 
access the Internet.

My question is what are the pros and cons of running a firewall on my 
client, e.g. is it really necessary.

I mean it's not like I am running Windows and have to bloat it with all 
McAfee, Zonealarm ad infinitum -- or do I?

Thanks alot in advance.
