Hey guys, I need your opinion on a firewall.

heres my setup

Satelite modem - 24 port cisco switch - users

Now its to the point where we need to have a decent firewall in place to keep our network secure. I need something that will be able to route traffic from the switch to the satellite modem for internet access, and be able to keep our financial data on the network secure.

our price range is up to $500

so after the firewall is in place, this is what it would look like

Satellite modem - firewall -switch - users.

Nothing to complex, just enough to improve our security.

The most important thing is for the users on the switch to be able to have access to the internet through the firewall. So I will need to be able to route traffic through the firewall to the modem.

Also something with a web based set up would be nice. lol I'm not to good with command line set up on cisco products. heres something I was looking at.
