Hi,

 

The ping DUP (duplicate) is the NLB cluster configurated in unicast mode.

 

So, the two server NLB have the same mac address (like 02-BF-...) and generate the brodcast traffic.

 

 

The problem, with the access to the virtual server from NLB proxy, is probably the conf of BIG-IP with auto_lasthop.

 

 

I have never tried these solutions, but there are these articles about this situation :

In my NLB configuration, there were two ethernet cards, and i have configurated the second card with a new IP in the same subnet/class,

 

and I have added a static route to the IP of virtual server from this second card with no NLB flag.
