Hi Blason,
There are two option for the authentication .
Use guest pass authentication: Redirect the user to a page requiring the user
to enter a valid guest pass before allowing access to the guest WLAN See
Working with Guest Passes.
• No authentication: Do not require redirection and guest pass validation.
You can create the L3 interface on the router if you don't have L3 switch.
Hope this helps.
Thanks,
Munish
