Plesk for Linux
kb: technical
Applicable to:
- Plesk for Linux
Symptoms
- Plesk and websites are unavailable
- All ports are filtered, except port 22 (SSH)
- The extension (D)DoS Deflate Interface was updated recently
Cause
The extension update installs the package iptables-services, which resets all the firewall rules.
Resolution
The issue has been addressed, and updating the extension will no longer reset firewall rules.
Manual Workaround
Install Plesk Firewall and enable it to automatically open the necessary ports.
-
Connect to the server via SSH
-
Install Plesk Firewall:
# plesk installer --select-release-current --install-component psa-firewall
-
Enable it:
# /usr/local/psa/bin/modules/firewall/settings -e
