[strongSwan] Authentication failure on server side

[Abulius, Mugur (Nokia - FR/Paris-Saclay)]

Hello,
A Linux server should log all successful and unsuccessful IKE authentication 
requests from clients. 
Does the up-down script gets invoked on the server side (which is always 
responder), if the authentication with a client fails?
If the up-down script is not invoked, there is any way to determine on server 
side from which IP address the authentication request was rejected?
Thank you
Mugur
