Why does Zyxel Keenetic 4G II guest access not work?

Question

WiFi

Hello! I had a problem, which, judging by the numerous questions on the forms, many faced, but apparently no one found a solution (or I just didn’t find it, but I honestly looked for it).
Guest access does not work on a freshly purchased Zyxel Keenetic 4G II router. More precisely, the guest access itself works, is configured, but it is impossible to go online from it, just connect. Yandex/Sky DNS is disabled in the settings. Thank you in advance for your help, having guest access in the store is very important to me, customers crave free wifi while waiting to order.

SOLUTION: (for those who will face the problem) In the command line mode of the router ( zyxel.ru/kb/1627), you must enter the command ip nat GuestWiFi

I have the first GIGA - everything works. does the device get an ip? which?
what ip of a piece of iron at a normal network? do both ping?
and show the trace to 212.45.25.70 - will there be a response?
