So everyone is talking about cloudflare tunnels and I decided to give it a shot.

However, I find the learning curve quite hard and would really appreciate a short introduction into how they work and how do I set them up…

In my current infrastructure I am running a reverse proxy with SSL and Authentik, but nothing is exposed outside. I access my network via a VPN but would like to try out and consider CF. Might be easier for the family.

How does authentication work? Is it really a secure way to expose internal services?

Thanks!

    I just decided to go ahead and implement split-brain DNS this evening and it works perfectly. What are you using for your internal DNS server? If it is Unbound, the one that I am using, I can share my config with you. After implementing this, the speed of my services when being accessed from my internal network sped up by an order of magnitude. I shoulda done this earlier. 😆

      That be amazing! I am currently not using anything (took down my homelab a while back) and planning on completely starting over fresh now.

      I am most likely going with unbound! So if you could, that be great!

        Here is a sample configuration that should work for you:

        server:
        interface: 127.0.0.1
        interface: 192.168.1.1
        do-udp: yes
        do-tcp: yes
        do-not-query-localhost: no
        verbosity: 1
        log-queries: yes

        access-control: 0.0.0.0/0 refuse
        access-control-view: 127.0.0.0/8 example
        access-control-view: 192.168.1.0/24 example

        hide-identity: yes
        hide-version: yes
        tcp-upstream: yes

remote-control:
        control-enable: yes
        control-interface: /var/run/unbound.sock

view:
        name: "example"
        local-zone: "example.com." inform
        local-data: "example.com. IN A 192.168.1.2"
        local-data: "www IN CNAME example.com."
        local-data: "another.example.com. IN A 192.168.1.3"

forward-zone:
        name: "."
        forward-addr: 8.8.8.8
        forward-addr: 8.8.4.4

        What makes the split-brain DNS work is if the request for resolution comes from the localhost or from inside your network, it will first go to the view section to see if there is any pertinent local data. So if you do a query from your home network, on say, example.com, it will return your internal IP address which in this case is 192.168.1.2
