Hi All,
I want to ask something about the case that I'm currently experiencing, here are the details:

We have SharePoint 2013 and we have a web application with internal URL
We have extended that Web Application and in the internet zone we set the URL with
Our goal is to publish the extended Web Application with IIS ARR Reverse Proxy, so that users can open the web application from external network.
is it possible to do this? if so, what steps should we take next?

Really appreciate for your response.

    Hi @Arief Hardiansyah ,
    You can refer to the steps below:
    Map the Internet side (public) IP address and TCP port to the inside (private) IP address and port. This is because your internal network will use private IP addresses that are not directly accessible on the Internet (10.x.x.x or 172.16.x.x or 192.168.x.x addresses). This process is known as network address translation (NAT).

    Set your firewall to port forward Port 80 to your internal server running SharePoint.

    When you made sure that you can access a web application, then you need to make sure that this IP is mapped to a domain name(using Alternate Access Mappings). Check the detail steps at here.

    Hi @YanliJiangMSFT-7045,

    Thanks for your advice.
    We already NAT our server ARR and we also configure AAM and configure extended web in SharePoint.
    However, until now we have not been able to access our SharePoint Portal, here is the error display when accessed from an external network
