Hey all. Ive been hosting some software for a while now, some private, some public stuff.
Recently ive gotten myself a domain name, and i’m trying to come up with a good way to have access to both the public AND the private on the same URL. Simpleton that i am i thought about putting the public in an inline frame with a banner with links at the top, but im sure there are better ways.
Any ideas how to do this from this community?
So I run windows AD and have windows dns inside and cloudflare outside. I also run NPM for the web prox in my DMZ.
On the inside DNS I point the A record for NPMProxy.domain.com to the IP of my npm server. I than setup service1.domain.com inside npm to forward requests to the web server setup for service1. I than setup the CNAME record for service1.domain.com to point to NPMProxy.domain.com. This should complete your inside.
Outside I set the A record on cloudflare for service1.domain.com to my public IP address which will route again to NPM. This will complete the outside connectivity.
Make sure your firewall rules are set and proper ports open and you should be golden.
For publicly accessible services, look into Cloudflare Tunnels. For private or restricted access services, add a Cloudflare Application to the Tunnel. The Tunnel provides a VPN connection without exposing ports on your router, and the Application provides authentication for access.
Something like this?
Not sure I fully understand your question or goal but you might benefit from setting up NAT reflection for your public stuff so when you are inside your nat you can still access everything with your external domain name like you are on the Internet. I see some people referencing split DNS also and that goes along with nat reflection.
docs.netgate.com/pfsense/en/…/reflection.html
There is a link to how you set it all up using pfsense.
Sounds like what you are tyring to do is called Split Horizon DNS.
Requests from outside your network should revolver server.domain.com to the public IP, but requests from inside your network should resolve it to the private IP.
If that’s what it is then you register the public IP with your nameservers. You also run a DNS service internally which you point all your computers at (likely by putting it as the DNS server in your networks DHCP settings). That DNS server is set up to return the private ip addresses for all your servers, and to forward any other requests to some external DNS like 1.1.1.1
Not sure if I completely understand but I think you want public service 1 accessible on subdomains s1.domain.com and internal service 2 on s2.domain.com?
Just point the A record for s2 to an internal ip address (or a tailscale ip). The only thing dns does is translate a (sub)domain to an ip address. So outside of your network s2.domain.com wouldn’t resolve but inside your network it would.

Or just louse one, and then run a local DNS resolver like pihole or AdGuard home and just make a record for the same host locally. The local DNS resolver will resolve the local request before it reaches the public DNS.

That’s what I did:
*.selfhosting.domain.tldthat points to my router’s IP address, which then redirects to an nginx+certbot reverse proxy*.local.domain.tldthat points to my local IP with CaddyThe only challenging part was to configure Caddy to issue SSL certificates using the DNS challenge since
*.local.domain.tldisn’t exposed to the outside world.TvanBuuren@lemmy.world 11 months ago
subdomains would work, though ive never worked on it without a gui. Time to do some learning i guess :)

OK, I didn’t read before answering, probably ignore my answer below but I’ll leave it up incase someone learns something from it.
