I have a remote office 10.101.0.0/24 connected to Azure network 10.0.0.0/16 via IPSec vpn. The connection appears to be solid 90% of the time, but it will sporadically start dropping packets. The configuration has been gone through a dozen times, the tunnel/SA always appears to be up on the juniper end. The configuration was based on the one available in the portal, as well as comparing it to another similar, working VPN.
There is another VPN connection to different hosting with a Juniper SSG which is up and solid. That SSG connects to all of my sites, in addition to Azure, with no issues.
I'm at a loss on where else to go with the configuration on the Juniper side, since the connection appears to have negotiated properly and is working most of the time.
