WLC9800 AP Clients can't talk each other in same SSID

[eeebbunee]

Hello Professionals,

I realized that my wireless end users can't ping or talk( such as RDP) each other when they are in same SSID.

Could you please help me to setup so that my clients can ping or talk each other..?

- WLC: 9800 (OS: 17.13.01)
- SSID: (Advanced)

Thank you for your attention.

You use p2p block I think this is reason

Hello Sir,

Then how should I fix to change config..? 
However, even though I choose the P2P blocking action to others (Drop, Allow private group, Disabled), none of them make clients ping..

This Flexconnect or Local mode AP
if flex central or local switched for SSID

if you connect the 2 to a wired connection same VLAN as the wireless do they work as seen more often ping disabled at OS FW level
