Greetings,
my current ISP refuses to provide me a static IP and they also blocks incoming connection to my ipv6 so I can’t host services on just ipv6 too. I will be changing my ISP when the plan expires.
without public IP I can host my own IRC bouncer but I would like to know what else can I self host? Thanks in advance!
softwares
That’s like ‘traffics’ and ‘manies’ and ‘mails’, right?
I just use a DDNS updater. That’s honestly good enough for most purposes.
Alternatively, you could use a service like Zerotier, Tailscale or Netbird to create a virtual private LAN connection to a free Oracle VPS, then route the traffic from the VPN to your home network.
Tailscale or Cloudflare will solve your problems.
Put everything behind Tailscale or another VPN and use it that way from outside devices. There should be very little need to have a public IP, and if there’s something that has to be exposed, use ngrok, cloudflared or Tailscale Funnel.
Anything
I use cloudflare / cloudflared agent to provide features hosted locally
Basically everything. Self hosting doesn’t rely on public access.
Rent a VPN, setup a wire guard tunnel and fuck your ISP!
Anyway having a real public IP on a residential block is basically impossible anywhere but in the USA, I guess.
Public IPV4 here. It’s not static, but very rarely rotates. DDNS ftw.
Telus Residential in Canada.
Literally anything you want. You don’t need a static IP, any dynamic IP with a software updater will work. For example, I have some public sites proxied through Cloudflare, and I use the DDNS updater for Docker that keeps my DNS correct.
The ISP is blocking his ports too, it seems.
Should check which ports.
Mine blocks 80 inbound and 25 outbound, but everything else I’ve tried works. (so no default http, and no outbound email)
I only really want 443 for simplicity, everything else can be random ports.
That’s an odd thing to see these days. I didn’t know ISPs still did that. I bet they offer a more expensive tier for businesses is why.
In my country no ISP will offer you a real IP address anymore. Not on IPv4 at least. So doesn’t matter if your ports are blocked or not, you are CG-NATted in any case.
Self host all your stuff and use tailscale if you just want to provide private services to yourself
I just have a script that checks my IP every few minutes and changes the DNS record as necessary
Anything. You don’t need any services to be public unless you choose for them to be.
actually I was thinking about hosting my own fediverse service to own my data but I can’t do that without a static public IP and domain name.
As long as you’re not behind CGNAT, you can use a dynamic DNS provider (like duckdns.org) and its web API to keep a record pointed at your IP. If you’re behind CGNAT, Tailscale also has a service (Tailscale Funnel) that can expose an internal service to the internet.
You could also pay for a small VPS with a static IP, and set up a Wireguard tunnel to your home server and an HTTPS proxy to forward traffic through the tunnel.
Also, just in general, use Tailscale. It’s serious black magic fuckery on the firewall.
I tried using DuckDNS for a while for DDNS, but noticed it seemed to have frequent periods of a few minutes each when it just wouldn’t resolve. Also was unable to get a matrix/synapse setup working behind it. It’s handy as a free service and nice if you just need basic DDNS, but it’s not the most reliable for hosting stuff from my experience.
I eventually settled on buying my own domain. Was much cheaper and easier to figure out DNS management than I was expecting, and my hosted services run so smoothly now.
Yeah I am behind CGNAT so I guess I have to use either Tailscale or wireguard as other users also suggested.
Thank you for the reply!
@whoareu cloudflare tunnel can easily help you do that. the only limitation is your domain will need to be from cloudflare. It works well, I am hosting an instance without any public IP and without exposing any ports.
Your domain need to be tied to cloudflare you don’t need to buy one from them. I just moved mine to them didn’t pay them a dime
You can use Tailscale, you can access your personal services with it but also expose public services with their Funnels system.
Keep in mind that while the clients are open source, their servers are running proprietary software.
I started using headscale (the opensource reimplementation of tailscale server) on a private vps. It is incredibly better compared to plain wireguard. I regret waiting so much before switching.
Something that really made my life easier: wireguard is poor at roaming: switching to and from my wifi created issues because the server wasn’t reachable anymore from its public ip and wireguard didn’t bother to query the DNS again to check the new IP. Also, configuration is dead simple because it takes care of iptables for you (especially good when you enables forwarding to a node).
Since the server just sends small messages for the control plane and all the traffic is p2p between the devices, the smallest vps with the smaller connectivity is more than enough to handle it.
As someone in a similar situation I’d recommend using a free tier oracle vps with a wireguard tunnel to connect to you services. Effectively just using the vps as a proxy for your own network. Here’s a guide that should work for your purposes https://github.com/mochman/Bypass_CGNAT
The best way would be to use a VPS to proxy your traffic to you. You can achieve this for pretty cheap, just set up an wireguard tunnel to a cheap VPS. That’s exactly how I access all my services from outside my home. As long as the VPS has a publicly accessible IP (most of them do), you being behind CGNAT should not be an issue.
This is the way OP
my current ISP refuses to provide me a static IP
So then use dynamic dns? HurricaneElectric offers DynDNS now and it’s great. You can update it right over
curl
if you want. I have it mapped to a cli function;~\downloads ❯ ddns HTTP/1.1 200 OK Cache-Control: no-cache, must-revalidate Content-Length: 18 Content-Type: text/html Date: Tue, 25 Feb 2025 09:24:18 GMT Email: DNS Administrator <[email protected]> Expires: Wed, 25 Feb 2026 09:24:18 GMT Server: dns.he.net v0.0.1 nochg {ip}
It’s not only not static It’s firewalled too! I can’t ping it from outside the network
You don’t want to expose services to the internet
Did you configure NAT to the service(s) and/or DMZ to your internal server in your ISP’s router?
Not allowing even ping seems like it is against any sane networking configuration.
Oh, damn. Not much you can do then. You may be eventually be able to get something outrageously complicated to work, but honestly it’s just plain not worth it. Just get a cheap VPS.
Best you could do is a forward server with tailscale and a reverse_proxy, but I’ve never had any real luck getting that type of setup to work reliably.
