I have Mutiple portal for different users and the SSID is open so anyone can connet but they have to pass the Portal auththication to access the internet.. so that i have notice is that when a device connect to anyof the SSID it redirectis to the admin ip which is the controller ip in the url.. so now if i apply ACL filterring then will it effect the portal opeing page ? how to correctly setup the ACL Filtering so that no other user in the network Vlan or in SSID cannot access the any device ip but can acceess the internet

What you asked contradicts to portal works.

It will affect the portal page.
