We are using a Cisco CSR 1000v router for our VPN connections into Azure. We are having issues with one of our clients that is using a Cisco ASA device. If traffic is initiated on our clients side the tunnel will come up but the encrypted traffic does not make it to our server. If we start a persistent ping on the VM in Azure then we can get traffic to pass. We have the user defined routes set in the Azure routing tables and have verified the configuration on both devices match. Any suggestions will be greatly appreciated.
Thanks, JAdams
