Hi,

 

that's pretty easy, Ping towards a VIP will never be answered from the Poolmembers, but only from the VIP itself.

 

And as the sourceIP of the Ping-request is unknown for your BIG-IP (not directly connected) it uses the configured route (10.10.10.0/8 -> 10.10.10.3) for the reply. To reach the next hop 10.10.10.3 it uses its own IP from that network, which is 10.10.10.50.

 

So everything works correctly as designed ;)

 

 

Ciao Stefan :)
