Firewall & Cisco 1417 Router

[tntsysmgr]

We have a small office network (50 users) connected to the internet with DSL via a Cisco 1417 Router.

What are firewall options. We have a mail server, web server and FTP server that will need to be "visible" to the outside, but none of the production servers or users should be.

Can I add, for example, a Linksys broadband router between the 1417 and the network. It is inexpensive and appears easy to configure?

depending on what your willing to spend there are a few options.
first: is obviously a dedicated real firewall machine(unix preferred, you can really lock that platform down) running firewall software such as checkpoint fw-1. PRETTY EXPENSIVE

Next would be a cisco PIX (firewall box) REALLY EXPENSIVE

or upgrade your ios memory depending to one of the ones below.
