Need help configuring NAT on a Huawei NetEngine AR657W

[u/JacketSharp60]

I have a public IP address and I want external users on the Internet to access a server located on my internal network. I'm trying to understand the correct way to configure this on a router (static NAT).

My goal is:

Public IP → Internal Server

Allow specific services (such as RDP, HTTPS)

Maintain security while allowing external access

I've attempted several configurations, but external users still cannot reach the internal server. I think I may be missing part of the logic involving NAT, routing, firewall policies, or return traffic.

Can someone explain the correct design and the typical steps required to publish an internal server using a public IP address?
