My ISP doesn’t give a Public IP and let me open ports without paying a extra fee, which I cannot afford rn. I host all my services on a old PC, Anyways that i can access my services beyond my LAN?
If you have IPv6, those are public and usually static.
Tailscale and Zerotier might be suitable for this, and they’re free for personal use. The can be used to work around NAT because they can route your traffic over their transparent relays.
That’s Really Lovely to hear and I am just a tad bit curious, How can someone make sure that the relay’s are transparent? You cannot really go and check it there to find out, can we?
Transparent here means the use of the relay is invisible to you. If two devices under the same tailscale/Zerotier network can access each other (e.g. in the same lan), then the relay won’t be used. But if both devices are under separate networks (e.g. one in your home, and the other is your phone while outside your home, and both devices are behind NATs), the relay will be automatically used as a bridge so both devices can communicate with each others.
Connections to relays are encrypted, but Zerotier allows you to setup your own relay server if you worry about privacy. Not sure about tailscale.
You have a few options. Depending on what your trying to do you could look into Tailscale or ZeroTeir. Basically they create a small VPN that you can join multiple devices to. This won’t open the services to the public internet but it will open the services to whatever devices join your private Tailscale/ZeroTeir network running over the public internet.
Someone already mentioned but CloudFlare Tunnels would be a really good fit as well.
Another option but more expensive and most complex is rent a VPS in the cloud somewhere setup a VPN link between the box and your PC and then route the traffic thought that VPS. All public access will hit your VPS public IP and port numbers and get relayed though that back to your PC.
Is that last one almost like a reverse proxy?
