HI brother im able to see the connection in the connection table once i changed the type of the VIP from {standard} to { performance layer 4}.  

 

 

But unfortunately another issue appeared where the website is not loading. But im able to see the connection table 

 

client IPaddress                     VIP ip address     floating ip address    node 

2a:45:33.xxx                         2a:66:x.x.x.xx             172.16.1.1                  172.16.2.3

 

 

I thought the issue might be related to SSL certificate. If there a way i can assign ssl on the performance layer 4 VIP. i didnt find an option for assigning  ssl certificate to it.

    Hey, 

    Performance l4 VS like the router , it just routs traffic from outside to inside, 
    you can't assign a ssl profile in performance L4 because you haven't any L7 visibility to parse the http Traffic. 

     

    have you added a IPv6 selfip address in the external VLAN ? 
    Take a packet capture and show it to me and revert back to standard virtual server.

    Review the Routing on F5 Bigip specially the back route for IPv6 Clients or enable "auto-last hop" feature in the virtual server.

    seems you have a missing route in F5 Bigip so auto last hop can help in this. 

    Try it and let me know
