  The key lesson is that with a research university, possibly all higher ed, there is no way to know everything our faculty and 
staff have cooked up when the rules were less strict. I strongly feel you have to put a device in place without rules to 
determine what "default deny" would reject, before turning it on.

+1.

When we moved from open to closed, I put the firewall in a log-all state for months before throwing the switch. I was then able to work out what everything was, write appropriate rules, interact with the appropriate sysadmins, and make for a very smooth conversion from open to closed.
