pool members can't connect to another Virtual Server

Hello,

for sure this is a problem already addressed but I have an issue with a client that is part of a pool behind a Vip. If from this client I attempt a connection to another Vip I get no response while the connection works in case I make the connection to my Vip.

My client route to the Vip network is the F5 interface. Is there something wrong? I am attaching a diagram that is maybe better than a thousand words....

  • Hi rosarra , 

    - Check the allowed Vlans in the Virtual server that you don't receive responses from it.

    - enable auto last hop feature in the Virtual server that you don't receive responses from it.

     

    You can take a pcap for impacted VS and share it if this available with you
