1. У вас, похоже, настроен Local forwarding. покажите /caps-man datapath print
2. А в логах пусто?
Пример моей конфигурации, где трафиком рулит контроллер:
[admin@ROUTER-NAME] > /caps-man configuration print terse
0 name=ctl-private mode=ap ssid=private-network security=security-private datapath=datapath-private channel=10
1 name=ctl-public mode=ap ssid=public-network datapath=datapath-public channel=10
[admin@ROUTER-NAME] > /caps-man datapath print terse
0 name=datapath-private client-to-client-forwarding=no bridge=bridge-private local-forwarding=no
1 name=datapath-public client-to-client-forwarding=no bridge=bridge-public local-forwarding=no
[admin@ROUTER-NAME] > /caps-man provisioning print terse
