@Tonybell You need to use the cable connect the Client CPE LAN port to your router's WAN port, and better use the router as access point mode in case there is double NAT in your network.

@antonioabb You can set a static IP address for this PC, then create an IP Group for this IP address and later set a Policy Routing entry. Take a look: How to configure Policy Routing

@Eric-jones12 The function you wanna use I think is Policy Routing, check this: How to Configure Policy Routing

@AlexNguyen Ping is working but it says Disconnected, most likely the firewall or anti-virus software has blocked the port, try turning off the firewall and anti-virus software.

@LeonardSitongia You're welcome~

@AlexNguyen Disconnected means there is a connectivity problem between the EAP and the controller, suggest checking if the EAP and controller can communicate with each other? Try pinging the EAP's IP...
