<hr>The question still remains.How much protection do you need and also what is more important.Your out going firewall or stopping the malware ect at the front gate.<hr></center>
You need as much protection as you feel comfortable with.
If you are secure in the knowledge that you never go anywhere "dangerous" on the internet (even though hackers use legitimate sites to plant some of their mouse-over code that activates when you pass your cursor over a spot on the site) and everyone you communicate with via Instant Message or email is equally diligent in their surfing habits and never has opened any spam or forwarded an email that has multiple senders or recipients that are not know to them personally (from whom a spammer or hacker can harvest your email address and begin their particular brand of assult on your system via the World Wide Web)......... well, I think you understand where I'm going.
As far as which is more important, inbound or outbound traffic. The answer is that they are equally important. You simply can't be absolutely sure that you will stop all the demons at the gate and if they get in, you don't want them calling all their friends and having a party with your PC and your data. IMHO, of course. <img src=/S/smile.gif border=0 alt=smile width=15 height=15>
