Version 4.2.5 bug fixes



Support reference 82714

Issues regarding the interruption of IPsec tunnel negotiation or the sudden shutdown of the IPsec tunnel manager have been resolved after updating the tunnel manager and an idle timeout was defined for it. These issues also generated "ignoring IKE SA setup: job load of XXX exceeds limit of YY" entries in IPsec VPN logs.

Support reference 82370

Support reference 82211

This issue can now be fixed by changing the value of the UseAutoFastRoute parameter to Off with the following CLI/Serverd command:
