Lifetime - (Rekey margin + random value in range (from 0 to Rekey margin *
Rekey Fuzz/100))
The default exchange of keys is in the following time range:

Minimal time: 1h - (9m + 9m) = 42m

Maximal time: 1h - (9m + 0m) = 51m
We recommend that you maintain the default settings. When you set key exchange
times higher, the tunnel produces lower operating costs, but the setting also provides
less security. Conversely, when you reducing the time, the tunnel produces higher
operating costs, but provides for higher security.
The changes in settings will apply after clicking the Apply button.
