# 1. Firewall: prima SSH, poi la porta di WireGuard
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
# Nota: le porte pubblicate da Docker aggirano ufw. Aprile/chiudile anche nel firewall del provider.

# 2. Crea la cartella e incolla il o i file generati
sudo mkdir -p /etc/docker/containers/wg-easy
cd /etc/docker/containers/wg-easy
sudo nano docker-compose.yml

# 3. Avvia wg-easy
sudo docker compose up -d
# Segui i log (Ctrl+C per uscire)
sudo docker compose logs -f wg-easy

# 4. Apri il pannello: https://wg.example.com

# 5. Dopo l'accesso, togli le righe INIT_* e rilancia docker compose up -d
