Wireshark when using APM

Hi

 

does anyone know if it is possible to run Wireshark when connected to a VPN using APM. I have tried this but found that once I start to run Wireshark any pings or anything else to my corporate network get dropped whilst attempting to run the capture. As soon as I stop the capture, pings begin to respond again.

 

anyone seen this behaviour or managed to get this working?

 

Thanks

    Dave,

     

    I see the exact behavior . F5 support suggested to increase the vpn suffer size for the db variable, but i still see the issue.

     

    Try to select the VPN interface in the wireshark and run the captures, you will notice all the existing open connections will be lost, when you turnoff the captures , you will see the connections get restored.
