subdomain redirection to an external domain on specific port (server uses noipcom)

[N3T]

Hello I have faced a problem.

I do own a domain mydomain.com that is added to my account on hosting with directadmin.

And i do have a stage server (for beta testing of code) in my local network that has got dynamic IP on my local gate/modem (cable network)

I do have configured router (routers) with dynamic dos service from noip.com and everything work well, and my local server is available under the address for example testpanel.ddns.net

So i can access the service that i'm coding using that adress. also i have redirected ports that when i use testpanel.ddns.net:8081 (port8081) i do see my panel i'm working/coding and testing right now (server uses ubuntu server 15 LTS)

Now i want to create a subdomain on my server where my domain.com is located, i want it to be called panel.mydomain.com, that is easy, and already done.

But there comes the tricky part:

I want to redirect all incoming traffic that points to panel.mydomain.com to my test server that is available under testpanel.ddns.net on port 8081


Is it possible do do that in direcadmin panel, and if so , than could someone throw me a bone where to manage the configurations, and how exactly i can do that ?
I'm using DirectAdmin 1.43.3

I'm waiting to any suggestions.

You need to craete a custom httpd configuration for your domain. You will need to proxy the subdomain to your DDNS.

It should be something like this and it should go on custom httpd configuration (DA Admin Level):

   ServerName panel.mydomain.com
   ProxyRequests Off
   ProxyPass / http://testpanel.ddns.net:8081
   ProxyPassReverse / http://testpanel.ddns.net:8081/
