As most others already pointed out, you have a wide variety of possibilities to choose, and it is very hard to give some recommandations, especially as none of the readers here has the necessary background knowlegde about what you want to protect and against which kind of attackers. Step back and think about it. A firewall is not a piece of hardware, but a sheet of paper that contains information about your threats, how dangerous they are, how likely they will occur, and how you want to protect against them. This last part can be achieved by simply not connecting your network to any public network, because you can't protect it sufficently, or you can rely on something called a packet filter, or application level gateways. When your security concept contains something called commonly "firewall", you have to decide which one to choose. As I already mentioned, there are lots of different solutions available, from very cheap ones to very expensive ones, and you have to consider a lot of factors. I hardly can suggest using a linux box if you (or anyone at your site) has no or not much expirience with linux at all. Chances are very likely that you can't achieve what you want to, and instead, a Cisco box, though much more expensive can be a better protection, especially when you are very experienced with that systems already.
