# 1. Firewall: zuerst SSH, dann der WireGuard-Port
sudo ufw allow OpenSSH
sudo ufw allow 51820/udp
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw allow 443/udp
sudo ufw enable
# Hinweis: Von Docker veröffentlichte Ports umgehen ufw. Öffnen/schließen Sie sie auch in der Provider-Firewall.

# 2. Ordner anlegen und die erzeugte(n) Datei(en) einfügen
sudo mkdir -p /etc/docker/containers/wg-easy
cd /etc/docker/containers/wg-easy
sudo nano docker-compose.yml
sudo nano Caddyfile

# 3. wg-easy starten
sudo docker compose up -d
# Logs verfolgen (Strg+C zum Beenden)
sudo docker compose logs -f wg-easy

# 4. Panel öffnen: https://wg.example.com

# 5. Nach dem Login die INIT_*-Zeilen entfernen und docker compose up -d erneut ausführen
