Im not sure if im doing this right but I am trying to limit certain devices on the network using a R600 but everytime I apply the policy on the WLAN, it limits all the devices thats connected instead of just certain IP's.
Under IP based User Defined Application;
IP Address: 192.168.1.21 (local ip)
Netmask : 255.255.255.0
I then create an application policy
Rule Type: Rate Limiting
Application Type: IP based User Defined Application
Could you provide screenshots of the WLAN configuration and show where exactly you are applying the application policy.
As per my understanding, you are creating a application policy which will only work for the traffic coming from/to 192.168.1.21 with port 443 (TCP). Anything else using this IP will not rate limit. I suggest NOT to use the policy this way, as it will not work as you are expecting.
