Authentication for connection security rules can be based on Kerberos in an Active Directory domain, or on certificates or preshared keys. This is the information maintained about a secure encrypted channel on the local computer or device, so that this information can be used for future network traffic to a specific remote computer or device. To change the computers that are in Endpoint 1 and Endpoint 2, select the Computers tab. This is where you get dirty and edit any parameter, no matter how small, for any rule and exception.
