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.
