And if you don't have an unique public IP address, for example because you are behind CGNAT, you can use Pangolin. It tunnels all traffic from your homelab to a VPS via Wireguard and exposes your services via a Traefik reverse proxy. Pangolin also automates the Traefik setup and provides a webui to configure the individual proxies.

For a VPS I recommended ionos, because they offer servers with unlimited traffic starting at only 1€ per month with server locations in both Europe and the US.
