Sophos XG to Azure VPN drops randomly

S248

I have a Sophos XG appliance running a site to site VPN to Microsoft Azure Virtual Network Gateway. The VPN randpmly drops and reconnect at random times for random periods

I have followed this guide, including disabling re-key and setting the DPD peer disconnection to disconnect: 

Any ideas what could be causing this?

    This was resolved by ensuring there is traffic constantly traversing the VPN. When there is no "interesting" traffic at all traversing the VPN the Azure side will send a delete request to the XG after about 15mins. Also noticed if the tunnel is down and you initiate traffic from Azure the tunnel comes up straight away.

    Still a bad behavior from Azure... But you actually can force XG to send keep alive through the Tunnel. Simply create a new gateway and send ICMP heartbeats. Will this keep up the tunnel?
