I`m new to Webmin/Virtualmin, coming from Plesk.
So far I`m impressed about the functionality and did a setup of a new server with Ubuntu 16.04 and running the install.sh of virtualmin to have a clean install.
Everything works, except the fail2ban security. On my old server its setup with iptables, so I checked with iptables -L, but even after 6 or 7 forced wrong logins I couldn´t find my ip. So I searched for the firewall and found, that FirewallD is installed, together with iptables, called Linux Firewall in Webmin.
When I open Linux Firewall (iptables) I see this warning:
External managed rules detected. Activate "Directly edit firewall rules" or your firewall rules may break. Warning! It appears that FirewallD is being used to generate your system's firewall. Maybe you should use the FirewallD module instead.
How can I resolve this apparent conflict?
Hope you can help me on this topic.
