The certificates and private keys have to be in PEM format. As certificate it is possible to
use only certificate which has start and stop tag certificate.
Random time, after which it will re-exchange of new keys are defined:
Lifetime - (Rekey random value in range (from 0 to Rekey margin * Rekey Fuzz/100))
By default, the repeated exchange of keys held in the time range:
•
Minimal time: 1h - (9m + 9m) = 42m
• Maximal time: 1h - (9m + 0m) = 51m
When setting the times for key exchange is recommended to leave the default setting in
which tunnel has guaranteed security. When set higher time, tunnel has smaller operating
costs and smaller the safety. Conversely, reducing the time, tunnel has higher operating costs
and higher safety of the tunnel.
The changes in settings will apply after pressing the Apply button.
