How to open ports in ZXHN H208N modem from byfly?

Question

network hardware

Hello. The problem is that today I changed the modem and when I tried to open ports on the new modem, it failed.
I tried to open different ones, not only port 80. I did it
according to the instructions , the settings are like this joxi.ru/52aQNZoiGKJp32
Unfortunately, it didn’t help ... Is there someone who has the same modem and he was able to open ports?
I will clarify that everything is set up on the computer and earlier (in the morning with another modem) everything worked. IP address is dynamic, but I work through noip

Answer 1

It turned out to be my own fault, I didn’t notice that my computer received an internal IP address dynamically, after I set a specific network IP address, everything worked
