Very easy setup for someone with a little bit of network background. I am a developer with a small company and the Linksys met our needs for the short term. It is nice that you can route traffic based on port to specific machines inside the firewall. (ie Port 80>web server or port 25>SMTP mail server etc). Unfortunately we needed a router that could allow us to access multiple servers on the same port from the internet and the Linksys could not meet the need.(It does not have a routing table for IP) We ended up purchasing a $900 device that could perform this task.I would highly recommend this device if you don't have these specific needs.
