How to switch CFP from basic Firewall+Leakproof to Full Defense+

One of my Computer is using CFP, configured as Basic Firewall+Leakproof, i was wondering if in future if i want full protection from CFP+Full Defense+, do i need to reinstall it or can i just switch to Full Defense+ by adjusting some setting within the firewall setting?

Take a look under miscellaneous/manage my configuration/ select. Are there two entries, one for optimum security, one for network security? If so, Melih says only the settings are changed, so I think switching to optimum security should do it.
