I don't know if the tittle is set correctly. But the point is:

I have configured an DNS ([www.some-domain.com](https://www.some-
domain.com)) with cloudfare that allows me to enter my NAS over
internet. But how to route to my local IP instead of passing through
cloudfare if I'm connected to my router?

Because it still routing me through cloudfare even when I'm in the
local network.


It's a Mi AloT Router AC2350, Can I do somenthing there to do that?

You would need a local dns server and set that as primary dns server
in your local network

This is not dynamic routing. That's a different network concept.

This is called split DNS.

Depending on what you want to do, you will also need to setup a
reverse proxy for HTTPs with a local CA.

Lookup split DNS.

So, I guess I can run a docker DNS server where all my local services
are there and tell the clients that if they are in the local network
client can route directly?

And set my router DNS to that service, right?

I’ll take a look to that Split DNS, thanks for clarifying.

Can I change the title?

Yes, it will work depending on how your services handle https

Depending on what type of NAS you own you can also run a DNS Server
like Pi-Hole or AdGuard on it, then let the DHCP let DNS point to your
NAS as a primary DNS provider.


All DNS requests then get send to your local DNS provider, where you
set Redirection entries to local IP Adresses.


Depending on if you want to have the "same" experience, i.e. not
having to give a port number or encrypted transmission through SSL -
you'd those subdomain DNS entries in your local DNS Provider to a
Reverse Proxy, and have that one sent the traffic internally.

Since you're already using Cloudflare, you could very well send all
cloudflare traffic to a local ReverseProxy via Wildcard and send
traffic from cloudflare and your redirection to a single Ingress /
Gateway for your selfhosted services.

The domain is resolved through cloudflare as your nameservers are
setup with cloudflare. You can either route everything through
cloudflare or everything direct without cloudflare, but not one or the
other...

To direct traffic direct, just turn off the Proxy in DNS settings of
cloudflare (DNS tab, then edit the A record that has your IP, and turn
off the proxy switch)

Hope this helps
