Hardware firewalls?

Hi all, this is simply a query - I mean I use a router at home to stop the little nasty peeps out of my systems - obviously doesn't work - or should I have not said that - if I get any attempts from hacker sI will report you to the FPI - Fat Pigs Investigation.

Anyway I was wondering if you can get and people use hardware firewalls for there servers at datacenters as a more secure way of securing your servers? and if so what type of hardware firewalls - I mean can you just go out and get a 10/100 HFriewall or something or has it got to be special - 10/100 if the cable going into it only takes 100mbps?

Regards
