Hi. I'm having a problem with clients connecting to other clients or devices on the same subnet they are on.
It might have something to do with ARP. As when i ping another device on the client, the ARP entry shows as '00-00-00-00-00-00 invalid' (is not receiving the mac address of the other device)
but if a go to another devices on the same network Eg router (default gateway) and ping that client.... the router actually gets the MAC address of the wireless card on the client.
We have no special setup... WLC 4404 (not using LAG) 184.108.40.206. and APs are C1130
I'm a missing some setting on the WLC?
