Hello,
I have successfully created an IPsec tunnel to the MS Azure platform using an ASA 5515 running 9.2(4). Seems to be working normally, traffic is flowing in both directions.
However every 2 minutes there are multiple Syslog ID 713202 "IP = x.x.x.x, Duplicate first packet detected. Ignoring packet."
The tunnel does not drop, pings reply and there are no renegotiation messages.
Is this typical for Azure or could there be a configuration issue somewhere? There are about 20 other tunnels on this equipment, only the azure tunnel shows the error.
I relied heavily on this documentation to setup: https://supportforums.cisco.com/blog/12704101/site-site-vpn-between-cisco-asa-and-microsoft-azure-virtual-network
Thanks,
Dustin
