Select Enable Guest Network (for wired clients) to convert the OPT or P6 port (depending on your model)
to be a guest port and isolate it from the LAN/DMZ ports. Devices connected to the guest port are
allowed Internet access only and do not have access to networks connected to the other ports.
When the OPT or P6 port is not a guest port, then guest devices connected to that port can
communicate with all networks, including devices connected to the LAN/DMZ ports. If that is not your
intention, make sure Enable Guest Network (for wired clients) is selected and that guest devices are only
connected to the OPT or P6 port on the Zyxel Device.
