IM presuming you are talking about P2P users, I suggest you Block P2P or limit P2P in IP firewall filter. IF you want more helpt you need ot be more detailed in your outline of what you want. -Jordan
If you want to block users from connecting to your AP, go to Wireless/Registrations. Right-click on each valid user’s MAC address and ‘Copy to Access list’. You can Tools/IPScan to see which IP belongs to which MAC address. Once you have all your valid users in Access list, go to Interfaces/AP-interface and tick off ‘Default authenticate & forward’.
Now only users in your access list can connect and will therefore show up in your Registrations.
Is that what you want?
