Hi i have set up guest network isolated on deco mesh. X50-poe's i have noticed that i can still access my isp modem/router/dhcp server in isolated guest mode. i have tried both ap and wifi router...

@David-TP There is no 1.2.1 firmware update for the DECO X50 Outdoor. The latest appears to be 1.0.3 Does that mean it is not out yet? 1.0.3 to 1.2.1 seems a big jump
