[Name] Connection Type [Description] 
This field allows you to set the connection type to any of the following: Select Tunnel to specify a host-to-host, host-to-subnet, or subnet-to-subnet tunnel. This is by far the most common connection type. Select Transport to specify a host-to-host transport mode tunnel. This connection type is much less common, and would generally only be used if you are attempting to establish an IPsec connection to another host which specifically requires this mode.
