- Plesk for Linux
- Some particular rules are removed from iptables firewall on daily basis, while others are left intact
Saving of iptables rules does not help:
# service iptables save
Advanced Policy Firewall
(APF) is installed on the system and running:
# /usr/local/sbin/apf -s
Advanced Policy Firewall overrides iptables ruleset.
Advanced Policy Firewall has a higher priority and allowed to override iptables ruleset.
1. Connect to the server via SSH ;
2. Add required rules to APF configuration file /etc/apf/conf.apf in accordance to its documentation
