How do I encrypt SQL Server traffic with IPSEC?
Here are the 2 papers you need to read in order to determine the best route you want to go in order to encrypt your server traffic. The first route is server isolation,which is setting up secure communications between specfic domain hosts. The second is domain isolation which is slightly more relaxed in that the only real requirement for communications is that the hosts all be domain members (note these are simplified explanations). These papers all seem to be writen for the vista/2008 timeframe but the concepts still apply. To get to the settings use the windows firewall control panel and choose conenction security rules -> new rule. Look here for more details on connection security rules.
