Setting up DNS + NGINX properly to Internal Services

Hi r/selfhosted. I am working on setting up my selfhosted setup. I
have 8 machines, old Dell Optiplex 7040 SFF, set up with Proxmox. They
seem to work properly internally, but I want to expose some services
externally (Seafile). I own a domain, but for this I'll just use
[mydomain.com](https://mydomain.com). I'm having trouble understanding
how I should set up my DNS records for this.

How I want my network function:

* [internal.mydomain.com](https://internal.mydomain.com) \-> points to
my NGINX proxy manager instance
   * I have this done with port forwarding and an A record to my
external IP
*
[seafile.internal.mydomain.com](https://seafile.internal.mydomain.com)
\-> proxies my seafile instance
   * I have a record in NGINX proxy manager to point
[seafile.internal.mydomain.com](https://seafile.internal.mydomain.com)
to [192.168.1.30:80](https://192.168.1.30:80)

When I hit [internal.mydomain.com](https://internal.mydomain.com), I
see the NGINX proxy manager success page, but when I hit [seafile.inte
rnal.mydomain.com](https://seafile.internal.mydomain.com), I get a 404
back. Can anyone help my to understand how I should set this up
properly?

Have you created a DNS record for [seafile.internal.mydomain.com](http
s://seafile.internal.mydomain.com)? The A record for
[internal.mydomain.com](https://internal.mydomain.com) will not
automatically include subdomains.

Ah that may be where it is failing. I don't have a specific DNS record
for it. What type of record would I need and what should it point to?
Or is there a way to have a wildcard?

You would create it in the same way you created the
[internal.mydomain.com](https://internal.mydomain.com) record, except
you replace "internal" with "seafile.internal" under under host. If
you want you can also setup a wildcard DNS record by putting "\*" in
the host section of the A record.

Freaking awesome. I was able to setup an A record with that wild card.
Thanks for the help!
