After trying to set the firewall in ispconfig 3 my system hangs. The system hangs because no dns can be reached. After stopping /etc/init.d/bastille-firewall stop the system works normal. But the job queue has stopped. It hangs at Insert firewall... The /var/log/ispconfig/ispconfig.log shows No further jobs are done through the admin panel becuase the latest job Insert Firewall has a fault. I really don't know how to resolve the problem.
