i just upgraded to v6.11 today and i wonder why is there so much space in the IPSec settings.
marked the empty space in Red Arrow on the attached screenshot.
Choose auth method = “rsa signature hybrid” and you will see why 
got it…
but somehow the entire working of the VPN just stopped after the upgrade…
trying to find out why…
now next step…
Generate Policy…
the simple tick has been replaced with 3 options…
where is the tick?? 
You can read in the manual about new parameters
port-override is the same as “tick” in older versions.
