    Hello f5mkuDefault.

     

    What type of VS is the one you are pointing above (https://support.f5.com/csp/article/K55185917)?

     

    Could you check if you have 'translate-address' option disabled in your VS configuration?

     

    Regards,

    Dario.

Hello f5mkuDefault.

 

There is no an issue.

This traffic represents pool members probes, for monitoring their status.

 

Regards,

Dario.

    I have been using ltm for quite some time...usually when you do show sys connection the last IP address is the pool member...

     

    However for this case the last IP address indicated is the vip address..

     

    Show sys output indicateds like this:

    client 》vip 》snat ip 》vip

     

    Instead of showing it this way:

    client 》vip 》snat ip 》pool member

     

    I dont think it is normal so I wanted to know what could trigger this situation.
