+# DuckDNS VPS Routing Fix
+
+When routing `grajmedia.duckdns.org` through the VPS reverse proxy, the DuckDNS
+update script MUST target the VPS IP, not auto-detect the home server IP.
+
+## Problem
+
+The DuckDNS update script at `/opt/duckdns/update.sh` used `&ip=` (empty, auto-detect),
+so DuckDNS recorded the home server's public IP (`162.81.173.34`) instead of the
+VPS IP (`51.81.84.34`). Traffic was bypassing the VPS entirely.
+
+## Fix
+
+Hard-code the VPS IP in the update script:
+
+```bash
+#!/bin/bash
+echo url="https://www.duckdns.org/update?domains=grajmedia&token=TOKEN&ip=51.81.84.34" | curl -k -s -o /opt/duckdns/duck.log -K -
+```
+
+Also check `/etc/hosts` for local overrides like `127.0.0.1 grajmedia.duckdns.org`
+(kept for local access to avoid hairpin NAT).
