We use the fixed NAT feature. Students sometimes download copyrighted material which they're not supposed to, or do things they're not supposed to, then we need to be able to track back who was the user. Because it's on a NAT, we need a way to be able to bind the inside and outside addresses. This is why we use it. It is very easy to use. Both the GUI and CLI interface are consistent, which makes the ease of access throughout various constituencies possible. It's also well-documented and logical. These are the things that I look for the most in ease of use.
