We are setting up a backup web server (Windows 2000 web server with IIS) in a data center so we can implement a failover service. Can you guys recommend some low priced hardware firwalls from Linksys or other companies that work well. We will spend more money if we have to. I have heard about Cisco Pix firwall. I think all I need it for is to close all the ports except port 80 and 21. I would appreciate any thoughts and your experiences in this area.
