      @nashbrydges Also, take a look at this for SSL 😉

        @nashbrydges this is a prefect case for containers. One container for PiHole, One container for NGINX, and one container for OpenVPN for Mobile Devices 🙂

          @aaronstuder Yeah, I've easily got Nginx running with standard sites on Apache for example but in this case, I think the complexity comes from the HTTPS redirect and the fact that lighttpd syntax is different and I've not used it.

            @nashbrydges Maybe I am confused? Why are you using lighttpd? Are you setting up NGINX as a reverse proxy?

              @aaronstuder That's the web server installed by default with the Pi-hole script for the admin page. Nginx would serve as the proxy.

                @nashbrydges Oh, are you trying to use NGINX on the same system as PiHole.

                  @aaronstuder I have a separate instance running Nginx but regardless, why would you not recommend on same server? I see no reason why that would be a problem.

                    Now that I'll be testing Romo's script, I don't need to use VPN and I'd like to setup the admin page behind Nginx. Found a tutorial that allows admin page access using Nginx as a proxy but I can't get the HTTPS redirect to work right.

                    https://github.com/pi-hole/pi-hole/wiki/Nginx-Configuration

                    Anyone have a working Nginx config with HTTPS redirect for this?

                    Found this that shows how to setup Let's Encrypt with lighttpd but don't know enough to set it up for other proper security headers.

                    http://www.itzgeek.com/how-tos/linux/how-to-configure-lets-encrypt-ssl-in-lighttpd-server.html

                    I've only got it working with nginx http.

                    upstream adblock {
                            server 10.0.0.3:80;
                    }
                    
                    server {
                            client_max_body_size 40M;
                            listen 80;
                    
                            server_name adblock.domain.com;
                    
                            location /admin {

                      @nashbrydges Haven't set the script to run via cron yet. It is still is printing some strings to stdout while I fully complete it, plan to add a log file and redirect the output to it.

                      I'll focuse on finishing it properly for Ubuntu so you can properly test it.

                        But if you want to test is manually, I think is is working properly.

                        At least for dns and Ubuntu I think it does want @aaronstuder asked for originally. The idea of custom ports could be done as well, probably just adding a list of ports you wish to open for each domain.

                          Can you make this so I can set whatever ports I want? In the example I gave before I just wanted to do DNS but now my mind is spinning with other ideas 🙂

                          @aaronstuder Different ports per domain or just add a list of custom ports for all domains?

                            @Romo Same ports all domains, but then then maybe allowing all ports since we are restricting by IP address already.

                            Seems like:

                            sudo ufw allow from 123.45.67.89
                            

                            Would work?

                              Well that's gonna be much easier.

                              Just finished a custom-ports branch, that gives you the ability to specify ports and protocol (tcp/udp)

                                Added the allow all ports for a domain, it is also in the custom-ports branch if you wanna test it and let me know if it works properly for you. I'll merge it to master if it works ok and start removing everything that prints to stdout.

                                          I don't get the point of this. I mean it is a cool concept, but it is to much work.
