ArcGIS Enterprise Portal reverse proxy

We have set up ArcGIS Portal and configured a web adaptor, Everything works fine in the local environment.

We need to access it through a DMZ.

We have setup a reverse proxy on IIS, Everything works fine whenever we try to access the Portal through a URL like this

But as a company policy, everything public should have "/external" added to the URL

So the URL should be

I set a rule to exclude the "/external" part from the URL but I get a 404 error for a URL like this

It seems that some requests are sent without adding the "/portal" part of the URL.


Any ideas please about this?


Thanks in advance.

Does this Esri help article help? The web context URL is the first thing that comes to mind for me.

Thanks so much, @RyanUthoff  for your response.

I actually forgot to mention that I also set the web context URL but this didn't fix the issue.

Just FYI, I  got it working now by sitting three inbound rules on IIS. I hope someone has a simpler way of fixing this issue.

Thanks again.
