wanted to unlock a few ports but I noticed that iptables didn't seem to be installed the folder (/etc/default/iptables) was empty. Then I set up the system freshly and installed everything again again no Iptables Start script under init.d is available I try to start the system comes an error message. Does anyone else have this problem?
Greetings Christian
