I am needing to install a hardware firewall for a company with under 100 computers.

Each computer has its own public IP address.

This will be my first hardware firewall setup, but I have done many software firewall installs. I have also setup our company router (different company that needing firewall)

So I was hopeful maybe for some tips or some easy setup firewalls for the new guy :)

As said, each computer has public IP and I will need to allow certain ports for multiple computers to be open i.e. I need port 502 for a few different IP addresses to be open.

I pritty much want to keep it simple for starts, allow any outgoing traffic, but start the protection with inbound traffic.

I dont need the most complex high tech firewall out there. The way the company is setup now they are totally open to the world, so a decent easy to use firewall would be great for me!
 
And people wonder where all the IPs are going....sheesh! [evil]
First off, get a firewall in there and start using NAT. I highly doubt your that company needs 100 public IPs per computer. Plus once you get NAT working you can tell them how much money they'll save by reducing their cost with the ISP...[thumbsup2]

Quick lesson though....When it comes to security, block everything, then grant access that people actually need. Instead of starting with an open configuration, start with a closed one. Get what I mean?
Remember! Internet access only requires port 80(http),443(https),21(ftp). Also 53 (dns) if you don't have an internal DNS server set to forward....

Anway, to actually answer your question....
Cisco PIX is a great hardware firewall, but might be a little daunting for a new person...give it a shot if you want though!
Try cyberguard instead, I hear its got a pretty easy GUI, and can be up and running out of the box pretty quickly. They also have a trial period that you can use to see if it will fit the situation.

Others might have more advice on which HW FW to use though.
Good luck!

I've got experience with Netscreen and WatchGuard firewalls, and can recommend either of them to relatively inexperienced installers. I second the "get NAT going ASAP" advice, and I'd add that given that the 100 workstations have been exposed to the internet for a while, locking down outbound traffic (with an eye toward trojans phoning home and such) is not a bad idea either.

What's port 502, by the way?

port 502 is for modbus protocol...its a standard for power meter equipment (electricity)

thx for the advise...turns out I wont be in charge of a firewall (for now) but starting off with more limited scope just to boost them up alittle...
