Hi,
I'm trying to follow the docs for setting up Captive Portal, located here: https://docs.opnsense.org/manual/how-tos/guestnet.html .
Step 1 says to configure a new interface, but I cannot find the + button to add a new interface.
I already have a LAN, WAN, and Wireguard interface, but it won't let me add a new one for the GuestNET.
My current OPNSense version is 20.1.7. Is there something different in the new release?
Thanks,
syutbai
