Connection is not stable and seems to be dropping randomly

Hi ,

We have created a dynamic routing gateway in Azure and we are using a Juniper SRX 220 with version 12.1X47-D15.4.

Since this device is not listed as the supported device for VPN in http://msdn.microsoft.com/en-us/library/azure/jj156075.aspx

I was able to establish connection with using the VPN config file for SRX Series 11.4.

However there is intermittent disconnection and random drop.

I ran Azure gateway diagnostics using https://gallery.technet.microsoft.com/scriptcenter/Azure-Virtual-Network-2b4d0793

But really didn't help.

Any specific steps that needs to be performed be it on VPN device or Azure portal.

Please advise
