after updating webmin/virtualmin a new feature has been added “Bandwidth Monitoring”, Its very useful tool but in my system it not enabled.
Actually I have installed Configserver Security & Firewall and when I try to setup Bandwidth Monitoring follows as error:
Redirecting to /bin/systemctl restart iptables.service
Failed to restart iptables.service: Unit not found.
How can i setup “Bandwidth Monitoring” if I have installed “Configserver Security & Firewall”.
