      Сегодня утром отвалились все клиенты Open VPN с сообщениями в логе вида:

      VERIFY ERROR: depth=0, error=CRL has expired: C=XX, ST=XXX, L=XXXXX, O=XXXXX emailAddress=XXX@XXX.XXX CN=XXXXX, serial=75
      Aug 26 09:41:11 	openvpn 	50653
      OpenSSL: error:1417C086:SSL routines:tls_process_client_certificate:certificate verify failed
      

      Отключение CRL в настройках сервера\серверов помогает, но так поступать нехорошо.

      Ошибка проявляется не только в pfSense:

      Похоже, что может страдать и другой функционал, связанный с обработкой SSL, например:
      Many of my haproxy backends went down last week (ssl handshake errors) and diagnosing the issue was very difficult.
      A lot of trial and error, I narrowed down the backend SSL verification and CRL, as the culprit. I stumbled upon this issue after searching errors related to a downed OpenVPN client. Applying the patch here (obviously) fixed both haproxy and OpenVPN issues I was having.

      Для pfSense 2.6 разработчики выпустили патч:

      Ставится через пакет System Patches.
