# OS Firewall

## OS-Level Firewall (UFW / iptables)

If you are locked out due to OS-level firewall rules:

1. **Use web console** — Access your VPS via the web console from the Sumopod dashboard.

2. **Check UFW status** — Run `sudo ufw status verbose` to see if UFW is active.
3. **Allow SSH** — If SSH is blocked, run: `sudo ufw allow 22/tcp` or `sudo ufw allow ssh`.
4. **Check iptables** — Run `sudo iptables -L -n` to inspect raw iptables rules.
5. **Reset firewall** — If needed, reset UFW: `sudo ufw reset` (this disables UFW and deletes all rules).
6. **Re-enable with correct rules** — After reset, re-enable UFW with proper rules: `sudo ufw enable`.
