How to open port (25565) for PC?

Answer 1

Internet -> Huawei (192.168.1.1) -> (192.168.1.2) Zyxel (192.168.0.1) -> PC

Answer 2

I can’t understand your problem, if the Internet is obtained by autoatom on Huawei on this network 192.168.1.1, therefore the Zyxel router takes this address on the van port and already redirects to the subnet 192.168.0.1 and the rest are already 192.168.0.1..100 that’s all the rest of the devices on the network of the Zyxel router, and what can you not configure?
