@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.

@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.

The idea of custom ports could be done as well, probably just adding a list of ports you wish to open for each domain.

@romo I love your script! Thank you so much! Sorry I didn’t reply before somehow I missed your post
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 123.45.67.89Would 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.

@romo Thanks so much! Seems to be working to me
-
Merged branch to master, removed stoudout outputs and added ip changes to .log file
-
@romo Can you add centos 7 support? I would help be I don't know anything about python...
-
@aaronstuder I am working on it already, haven't had time to finish it yet due to other work. Will post as soon as it is ready.
-
I don't get the point of this. I mean it is a cool concept, but it is to much work.

What's not to get? This is being used to limit who can access the cloud hosted Pi-hole server to only those whose DDNS domain (and ergo IP address) is listed. It makes the server DNS access non-public for those with dynamic IPs who are setup with a DDNS domain.
Do you have another recommendation for limiting server access for DNS services to a limited IP that is dynamically assigned by the ISP?
I agree it's been a lot of work for Romo who's kindly provided us with the script but in the absence of a better solution, this is extremely useful.

I am going to be using it to give my friends and family access to a bunch of services I run, DNS, Nextlcloud, etc. That's why I had @Romo have it allow all connections from one IP
-
The point is there is no point to the entire DNS for friends and family thing.
