Hello Alessio.

When you try to access the VIP from the lan. Aint the "realservers" and the "clients" \
on the same ip network then? In a case like that you need to use DSR switching. \
Because the traffic from the realservers to the clients will not pass the \
VIP/loadbalancer, and it will not be able to the it´s address and port translation..

Regards Fredrik.
