I have a wifi router which is connected on the network. The users using the wifi internet can access my LAN network. How to block the wifi users to access my lan network and system. How to configure the wifi users to accesss only the internet and not the LAN.
Depending on your router model (which you didn't mention) you may be able to activate client isolation mode or guest WLAN mode. Alternatively, separate your internal network from the WiFi network by a firewall router.
