Firewall Help

I have questions about software and hardware firewalls. Someone suggested I post it in this forum, so if you've seen it another and are annoyed by me, I'm sorry!

What do you think about the Norton and Windows Firewalls? If there's something better, why?

I manage a small network of about 13 computers. We use wireless Internet from a local provider. Two computers are at this building.

We then transmit the Internet to a nearby building wirelessly using an wireless access point. The 11 computers at this second building all receive their Internet through CAT 5 from switches wired to the access point.

There is no data transfer or networking between the buildings. All the computers access the Internet and use email.

I would like to set up a hardware firewall at the first building. Would a PIX firewall be a good choice? What model? Can anyone give me advice on this?

Finally, to protect from external intrusion (forget about internal for now) is it necessary to run software firewalls if running PIX or an alternative? I'm guessing the more, the better, but is it too much?

I know it's a lot. Thanks!

P.S. Just to clarify-nothing is transmitted wireless within the buildings. They're all hardwired inside to access the network.

 

It's better to have good firewall protection, both hardware and software, for your business. Internet Firewall Router is recommended for office that use high-speed internet such as DSL or T1. It will protect against DOA(Denial of Attack) and hackers from breaking into your business networks. Firewalls Software like Symantec Internet Client Security or McAfee Firewalls is recommended for users who use the internet on workstations. It will protect privacy information inside workstations being exposed to internet world by infected sites or program.

 

Thank you for your time.
