The author describes a DIY solution for serving web from a homelab behind a volatile dial-up IP by using a cron job that polls connectivity and SSHes into a reverse proxy VPS to update its config when the IP changes. The approach avoids third-party dynamic DNS services, relying instead on simple shell scripting, curl, and SSH to keep the reverse proxy in sync within 15 minutes of a reconnect.
Background
Dynamic IP addresses from dial-up or consumer broadband connections remain a common challenge for homelab enthusiasts running public-facing services. Many opt for commercial DDNS providers, but some prefer self-hosted, tool-light approaches.
