New to Tailscale. Can I use it along with my own DNS and NPM to access my services externally using my existing internal custom domain? (lemmy.world)

I’ve not done much with external access in the past, but I’m playing with Tailscale and it’s pretty neat. Wondering if I can configure it to work like my local access does:

I use Nginx Proxy Manager to set easy subdomains for my services, I.e. service.mydomain.com
I use AdGuard Home and have a redirect for *.mydomain to that NPM
This works great internally, which is all I’ve really used it for.
I’ve got tailscale working and I can go externally to server.wackyname.ts.net:serviceport.
what I’d like to do is have tailscale somehow use the same internal dns/npm info so when I’m on my tailnet service.mydomain.com still works.
But no other external access, said subdomains do nothing off tailnet.
Mydomain.com is an actual domain I own. General DNS is at Cloudflare right now (main domain was pointed at a hosted site previously, but that’s not needed anymore)

Any way to pull this off without a ton of complexity?

Yes, also Tailscale already provides hostname dns for every device on your tailscale net.

I know it gives me their magicdns, like server.wackyname.ts.net, I'm talking about using my own domain.

slap the tailscale ips into your dns entries then. I do that.

Same. Works great

By default Tailscale devices prefer the local DNS server for any hostname that’s not part of your Tailscale network, unless you’ve configured a global DNS server. There’s also the option to configure split DNS and have a different DNS server for certain domains (for example your own domain). You can also add search domains to allow short hostnames to be resolved to FQDNs of your choice.
