I can see the app on localhost on either port 8000 or port 8081.  What am I 
doing wrong?

you app is being called by apache so it doesn't matter were it is  as
long as apache can reach it.

Your box doesn't LIVE on your router.  Is your box where the webserver lives 
assigned the
public IP address?

what is ifconfig on the webserver box?

This is what I have in the conf file at the bottom:
"

Options All​
Options Indexes FollowSymLinks​
AllowOverride None​
Require all granted​
​
​
​
ServerAdmin osmanzaki...@hotmail.com​
ServerName dragonosman.dynu.net​
ServerAlias www.dragonosman.dynu.net​
ErrorLog "logs/dragonosman.dynu.net-error.log"​
CustomLog "logs/dragonosman.dynu.net-access.log" common​
ProxyPass "/" "http://192.168.10.12:5501/"​
ProxyPass "/?q=accesskey" "http://192.168.10.12:5501/?q=accesskey"​
​
"

And I added a forwarding rule for port 8000 for the router.  But I still can't 
see the app at my public IP address on port 8000.

In ProxyPass, assuming your reverse proxy and backend are on the same
internal network, yes.
As long as the reverse proxy is port forwarded, and it proxies to your
backend, the app will be available on your public IP address.

Wait, so it's fine if I use my internal IP address?  The app will be available

Yes. But normally you would use an internal LAN address not a dyndns
kind of thing for the link between a reverse proxy and the backend.

Probably best to move it inside. At the moment, you only have 1
virtual host, so it doesn't make a difference.

No, the first parameter is the incoming URL prefix root you want to
forward to what's supposed to be the address of another HTTP server
(origin or backend server) in the 2nd parameter.

Your first parameter is a local filesystem path and it won't match any
request for / or /myapp.  No example looks like this.

It also looks like your 2nd parameter is the URL for the reverse proxy
itself, which would loop if the first parameter ever did match. For
the tenth time, if you don't have your application listening for HTTP
requests in some other server, you should not be setting up a reverse
proxy.

The httpd.conf file is attached to this email.  The VirtualHost and ProxyPass 
stuff is at the bottom.  Please let me know what I messed up now, if anything 
at all.  And if there's something wrong, help me out with that.

The first parameter to the ProxyPass directive for "/" is currently the 
directory on my computer where the doc-root of the app is.  It's also where the 
server executable is.  If that's right, should I also put that directory for 
accesskey route (i.e. /?q=accesskey)?

When I try to get to "localhost:8081" in my browser now, I get an "Index of /" 
page and nothing more (8081 is the port Apache is listening on).  Trying to do 
"localhost:8000" gives an error (8000 is the reverse proxy port).

This has nothing to do with port forwarding in your router.  "If"
you've set it up correctly, accessing the reverse proxy directly
should result in a HTTP request sent to whatever "other" HTTP server
you have that dictates using a reverse proxy at all.

Get it working on your LAN first.  The "correct" way to visit the app
is determined by what port your reverse proxy listens on and what path
you forward to your backend with the first parameter of ProxyPass.

I need to know if I've set up the reverse proxy configuration correctly in the 
conf file, and also how to fix it I did something wrong.  And I also need to 
know how to correctly visit the app in the browser after I've set it up 
correctly and am forwarding the port that Apache is listening (if that's the 
only port I need to forward).

Two ranges sounds like you can map it to an alternate listening (internal) port.

Unless your router allows you to forward port A to port B in the UI,
you'll have to listen on a port your ISP isn't filtering.

Re: [users@httpd] Port Forwarding Help?

[Osman Zakir]

I can't use port 80 or 433 for my external port because the router's using 
those ports.  8080 and 8443 are also being blocked by ISP.  So I had to use 
5501 and forward that.  I'll take away the forwarding rule for port 5501 if I 
can get the reverse proxy to work, though.

That being said, just now I tried to visit dragonosman.dynu.net:8000 after 
setting up port forwarding for port 8000, since I'm using that port for the 
VirtualHost setting in the httpd.conf file.  The file is attached to this 
message.

Do I also need to set up port forwarding for the port that Apache is listening 
on?  Because right now I can't get to my app in the browser through port 8000.  
On Chrome, I get this error: ERR_CONNECTION_REFUSED.  I asked on a Discord 
group I go to as well and one of the members there just told me that I only 
need to forward the port that Apache is listening on.  Is this correct?  
Because if so, I'll need to choose a different port because I'm having it 
listen on port 8080 which is being blocked by the ISP.

Re: [users@httpd] Port Forwarding Help?

[Yehuda Katz]

If your ISP blocks port 80 and port 443, there is no way for you to host
the site without a port number.
If you can run a server on those ports, HTTPD would listen there and
reverse proxy to the internal port the app is running on (5501?). You would
not want to forward 5501 through the router because it would allow people
to bypass your reverse proxy.
You prove ownership of the URL by placing a particularly named file in
/.well-known/ and the SSL tool will check for it there. This will not work
if you aren't on a standard port (80/443).
