Hi,

 

The BIG-IP act as a full proxy. So there are two TCP connections. One at the client side and one at the (backend) server side.

 

So the TCP connection at the server side comes from the self-IP of the server VLAN. In a cluster setup, this TCP connections comes from the float-IP.

 

To monitor backend servers, you can add a monitor to a pool and nodes. This monitor traffic comes from the self-ip address of the BIP-IP.

 

Hopes this helps.
