VPN Gateway Site to Site - Capture packets via connection

Hi community,

I have a question about an Azure VPN gateway and the Site to Site Connection.

Is there a way to see in logs which IP addresses are actually running through the VPN gateway?

I only ever find the IKE and ESP activities in the logs but nothing about the actual traffic that runs through the tunnel/connection.

I would be interested in specific queries to see whether these are pushed from an address range through the tunnel or not?

Thanks.

Best regards

Phil

    @Philipp Gerber ,

    Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

    I understand that you would like to see live packet capture on a Azure VPN Gateway

    You can consider packet capture for VPN gateways.

    • Please go through the schema, filters and the performance of the Gateway while you run the packet capture
    • Post collecting the packet capture, you can use tools like NetMon, Wireshark to analyse the packets.

    Thanks,

    Kapil
