I am getting better and better even I am still coughing sometime, but it’s not as bad as several days before or maybe I am already used to it. Anyway, I keep reading the book of MCSA/MCSE 70-291, today I learned Packet Filters, the concept is very easy that just set some holes on the firewall-sounds like a security problem, but you can’t do anything without these holes. Later on, I read Remote Access Connections and Remote Access Policies included the issues of authentication, encryption and authorization.
