This parameter specifies the type of connection to the corporate network and can take one of the following values
1. NoE2EAuth: No end-to-end authentication required
2. E2EAuthOnlyToAppServer: End-to-end authentication required only to the configured application servers and not to other servers in the corporate network
3. E2EAuthRequiredToAllServers: Access allowed only to the configured application servers via end-to-end authentication and no access to other servers in the corporate network
If  NoE2EAuth is specified the cmdlet automatically remove all the app server security groups and and Group Policy objects from the DirectAccess deployment and user has access to all the corporate network servers over a full tunnel to the DirectAccess server.
IPsec traffic protection is not applicable when the connection type is NoE2EAuth and hence cannot be configured
