Port forwarding for local requests

sectioni

Hello,

I have a Zyxel router with firmware version: V5.13(ABLZ.1)b10_20200422
I went to the NAT section and did some port forwarding rules, and they work when the request comes from outside the network.
If I try to access the IP and port from a machine inside the network it goes to the router admin panel.

How should I configure it properly?

The requests are for port 80

Found the answer.
I had to change the router's remote admin port from 80 and 443 to something else.
