What can I say, part of the OpenVPN config:

status /dev/null

log /dev/null

verb 0

Part of the IPSec config:

charondebug="asn -1, cfg -1, chd -1, dmn -1, enc -1, esp -1, ike -1, imc -1, imv -1, job -1, knl -1, lib -1, mgr -1, net -1, pts -1, tls -1, tnc -1"

(-1 means absolutely silent)

There are no client connect/disconnect scripts active.

Authorization, Accounting and Authentication log queries in FreeRadius are disabled.

All name server logging is disabled.
