I have a problem with a wireless client that it not able to ping a virtual IP of server in NLB modality.
The WLC can do a ping to the first physical, to the second physical IP and the the virtual IP correctly.
The Wireless Client can do a ping to the first physical, to the second physical IP BUT can not do a ping to the the virtual IP.
The WLC and wireless client have the same mac-table with the same mac-add of tree IP (2 physical and virtual).
When from WLC, i do a ping to the Ip virtual, I send 3 pkt and I receive 6 pkt (3 from first network lan and 3 from second network lan, I think...)
I think thet the WLC drop the pkts to wireless client to virtual IP of LNB Microsoft (NLB work correctly).
What do you think?
