which softwares can I self host without public IP?
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!
Self host all your stuff and use tailscale if you just want to provide private services to yourself
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.
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
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.
@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.
Look:
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;
cli

It's not only not static It's firewalled too! I can't ping it from outside the network
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.
I mean you can host anything. It's just not reachable from the outside. And Fediverse or anything that gets data pushed in, won't work. The common method to handle all of this is to use some tunnelling solution.
Use Cloudflare's free tier tunnel
They'll shut it down if you send more than a few megabytes down that tunnel. It's ok if you just need a connection (for ssh and stuff) but anything that generates a lot of traffic will be blocked.
If this is just for personal use, I'd see if you can put their router in modem mode and go get a better router, then I'd just use tail-scale or WireGuard.
tailscale is looking good I might try that
It's amazing additionally you can run Mullvad through it that might solve your public IP issues but I only run my services for me and my house
I believe duckdns has a tool that checks your public ip on a schedule to update your subdomain. (Which they provide for free last I checked)
That would solve not having a static IP, not solving having no port forward right?
You usually only need to specify the internal host ip to setup a port forward. It should forward that to whatever the public ip is at the time.
If the isp is providing the model/router and generally being oppressive i highly recommend researching if you can place your own router behind it.
