FW internal Traffic blocked on WiFi access

Question

Hello community, 
 again i&acute;m fighting a network problem with my WiFi-Clients. Maybe someone can shed some light into this case. 
 Symptoms: 
 The Computers cannot access WAN and LAN ressources. Logon process takes some time, due to unreachable DCs. Some traffic passing through FW while other traffic gets blocked for no reason, eg: 
 
 Port 11 is my LAN-Subnet (192.168.0.0/22). The IP-Adress 192.168.1.120 is a local server with software distribution who tries to access (but cannot) my laptop . 
 Some WAN-traffic goes through, FW-ID 2 is LAN-->WAN policy. 
 
 Firewall-Policy #2 looks like this: 
 
 Part2: 
 
 Question#1: Why is this local traffic marked as "Appliance Access" by the Firewall? 
 Question#2: Why is local traffic blocked ? Why can&acute;t the broadcast address of my network be reached? 
 I have a LAN --> LAN policy with only log activated, no IPS, Traffic Shaping or Web policy activated: 
 
 The Wifi Network is defined as followed: 
 
 Question: Do i need the Zone Wifi? In my opinion LAN-Zone also applies to Wifi-Clients which are bridged to AP-LAN. Am i correct? 
 
 Thanks for looking into this.

I have finally found a solution for this mind-boggling problem: 
 I ordered a testdevice of the new APs (APX-Series), now i&acute;m using the Cloud Controller for the APs and everything works as a charm. I was unable to fix this problem with the old APs (AP55C) in connection with the XG WLAN Controller - now it seems all good. 
 Try it out!
