Doubt about how to reduce the time of re-keying for 30 minutes (Perfect Forward Secrecy) in Viscosity

[TCalhau 4]

I wonder if implemented correctly the reneg-sec n command in Viscosity. See screenshot.

 

P.S.: I would like to reduce the time of re-keying for 30 minutes. I'm getting login normally on the server AirVPN. But I don't know if this line of code in the correct location.

 

I'd appreciate it if you can help me! =)
