Let’s say my server is running on a VPN and gets new IP once in a while. Would Pangolin be an option to publicly expose my services? Because I have this challenge now where I am currently ”forced” to expose my public IP to share some services. I use firewall rules to allow incoming traffic to my server and Traefik to route the user to the right service. I just don’t like the feeling of being exposed publicly like this.

You need a publicly routable address in the mix. You would need a way of knowing that address.

I have that same feeling with the self hosting I do. To alleviate the small amount of stress it would bring me I rent a VPS that’s public on the internet. I configure a persistent keep alive, on the client I run locally to keep a connection to the server open, no port forwarding needed.

Yes! Most people I think rent a VPS (some can be had for like $1 a month) and install this. Because it tunnels back to your network your network can be anywhere behind anything and it should hole punch to it. And because the public is visiting the public address of the VPS your network is hidden behind that!
