Not quite correct...a router has a built in firewall.
What firewall do you use?
Thanks everybody for your thoughtful replies.
I was wondering, after giving it some thought, how likely could an additional hardware firewall device cause ISP or computer problems? And is it something you can just plug in, or does it require some technical knowledge?
I asked the guy because almost no one I know of uses a hardware firewall. I'm no expert but it's my belief that sofware firewalls are infinitely better in terms of configurability. I know of no advantage a "hardware" firewall has over (for example) Zone Alarm. Firewalls block things. That's all they do. It's either "Pass" or "Block". I'd much rather have a software that is commonly used and easier to configure, to let things in that I (and most other people) want in, and block things that I (and most other people) want blocked. Plus you have to pay for it. Windows Firewall is free. I think there are other firewall softwares that are free. Hardware costs money.
As a novice, I recommend you make use of the free opportunities you have at hand before moving on to whatever "next level" there may be, where you are spending real money for the functionality of a hardware firewall that you may not even need.
