Selfhosted @lemmy.world LifeBandit666 @feddit.uk 8 mo. ago

Help a noob find what I'm looking for please. I have a bunch of IP addresses and I wanna give em names.

I'm using Heimdall to easily access my self hosted stuff ATM. I would like for my family to use them too if they're so inclined, but there's no way they will be able to remember the IP addresses, I know I can't!

Is it a DNS I'm looking for? If so, I'm already hosting a couple of instances of Adguard, can I just set it so that Plex is 192.xxx.x.47 and snapdrop is 192.xxx.x.53 and use that to resolve the request so my 13 year old can just type Plex into his browser and find it?

Or do I need something like Caddy or Nginx or something in between?

Thanks for any advice.

A proxy is the easy way in my opinion. You can also do straight up DNS, point your dns server to each of your IP addresses, which is by far simpler, but I prefer the nginx/caddy route.

NGinx will also handle things like SSL for you, which you can terminate at the proxy and make life a lot easier for you. So you can do things like register a domain, set up nginx to handle the certs for you, and then no more errors on "insecure connection", even if each underlying service is only using http. Plex was specifically nice getting that up, so I could finally do plex.my.domain.whatever and have it be nice and https. Inside the house it's nice, outside the house it's even greater, especially because a proxy can route those ports for you. So plex.my.domain.whatever goes to Plex, and tautulli goes to tautulli, etc..
- I WANT to learn how to do all that stuff properly but it hurts my brain. I WILL learn it at some point.
  
  But I have a domain with Cloudflare and found that far simpler than DuckDNS and Nginx .
  
  I intend to look into Nginx and caddy and learn them, it annoys me that it makes my eyes cross, but if I can just use Adguard for now then I shall do that, for now.
  
  I'm at a point where I know that the IT manager at work is a bit shit because the internal addresses at work have no certificate, but also that I'm not better because it makes my eyes cross too. I've done it before but I don't know how I did it, it was a lot of poking.
  
  nginx is a beast, I haven't used Caddy. What I'd say to a newcomer is stick to the plan, just do it step by step. Don't go looking to build a 30-service massive 1000 line nginx file immediately. Start small.
  
  Get the proxy running. Celebrate, have a beer.
  
  Proxy a single service through your new proxy. Celebrate, take a break.
  
  Proxy a second service through the proxy,.
  
  Set up SSL for those services.
  
  Set up each service individually.
  
  Trying to do it all at once will make you go crazy, I made that mistake. Focus on one small thing at a time, slowly adding to your config, that'll make it easier. Also make backups, or better yet store the conf in a git directory or something so you can easily rollback. If you have one service running but adding a second breaks it and you want to take a break, it's a lot better rolling it back to a known good state rather than leaving it in a broken state.
- If not using DNS, how are you directing traffic to nginx?
  
  Was referring to using DNS to each individual service rather than one single DNS point for your entire proxy. I have *.my.domain pointed to my proxy which directs everything underneath it.
  
  Ok so what I need to do in my case is have my DNS direct *.crypt to my Nginx (when I get it set up) then have that direct all the bits that the star represents to the right IP/port?
  
  Not *.crypt. say you buy mycooldomain.crypt. you then point the domain service that domain and *.mycooldomain.crypt to your public Ip.
  
  You would then forward the ports on your router (like 80 and 443) to your proxy. This will get your external users working.
  
  Internally you'll need to set up your local DNS so that it knows you are the mycooldomain.crypt. there are multiple ways based on what hardware and software You're running, do some googling. For me in my local DNS then I say *.mycooldomain.crypt points to my local proxy DNS, so that it resolves inside the network.
  
  So, external DNS points to public Ip, router/firewall forwards those ports to proxy. Internally your DNS will reach out to your router/DNS/whatever you use to ask what that domain is and it will respond with the local IP of the proxy.
  
  This is how I do it. It works internally and externally, though it's more than OP needs. :)
  
  To add to what's been said (in case it's useful to others), it's worth looking at SWAG and Authelia to do the proxying for services visible to the Internet. I run them in a Docker container and it does all the proxying, takes care of the SSL certificate and auto-renews it, and adds MFA to the services you run that support it (all browsing, MFA-aware apps, etc).
  
  Another thing I like about SWAG's setup is that you select which services/hostnames you want to expose, name them in the SUBDOMAINS environment variable in Docker (easy to remove one if you take a service down, for maintenance, etc), and then each has its own config file in Nginx's proxy-confs directory that does the https://name.domain -> http://IP:port redirection for that service (e.g. wordpress.subdomain.conf), assuming the traffic has met whatever MFA and geo-whitelisting stuff you have set up.
  
  I also have Cloudflare protecting the traffic (proxying the domain's A record and the wildcard CNAME) to my public address, which adds another layer.
  
  Ok that makes sense. I'm not trying to tie any of this to my external domain though, I just want to proxy Lan names at the moment.
  
  I have a domain set up for home assistant though Cloudflare and I don't want anything else to be externally accessible.
  
  So what I'm currently trying to do is have radarr.crypt, Sonarr.crypt, plex.crypt, openwrt.crypt hit the correct lanIP:port
  
  I can't do that with just my DNS because that's just for lanIP not port
  
  So I'm trying to have the *.crypt go to the Nginx IP and have that proxy the name to the IP and port.
  
  I've been prodding it all day and even had ChatGPT have a go at it but I'm getting nowhere.
  
  And this is why I don't like Nginx.
  
  I have managed to get Nginx working and even got a pretty UI for it, but just can't get it to proxy my IP addresses to names.
  
  It ain't a big deal, Heimdall does the job for now, just thought it would be a nice way to dip my toes in.

  Thanks, I've saved this comment for next time I try to do this
