Hi
We are running two Static Routing Site-to-Site VPN Connections from our on premise Sonicwall NSA 3500 Device to Windows Azure. Acutally both of them are running, but are experiencing regular (hourly) interruptions.

We have tried different settings f.e. Phase 2 Lifetime: 3'600 or 28'000 s or MTU Size 1404 or 1476 or 1500.
But still get this hourly connection interruptions.

I am aware that there are warnings showing in this log, but we are running the latest firmeware, and also ESP Algorithm and IPSec proposal are set correct.
May you have any suggestions to get this problem fixed?
