I have a Virtual Network Gateway configured for Site-to-Site VPN to a local network. We have an intermittent issue to/from one specific local network. Ping tests result a minimum of 4 consecutive request time out and occurs more
often than not. Traces indicate the trouble-spot is between the GatewaySubnet and the Tunnel. It's also the gray area as I don't have any further visibility. The test is an ICMP request from the local network destined to a virtual machine in the
VNET. This VM using a packet trace shows that it sends ICMP replies with every request. How can I troubleshoot this?
