Hello Volker,
I was very busy with studies yesterday. But I got to install firewall builder. I am a bit confused on how to use it. Will it use the existing iptables file or make a new file for it. I get some errors too.
They are
1. When I start the application with command fwbuilder.
[root nessusClient root]# fwbuilder QSplitter::setProperty( "handleWidth", value ) failed: property invalid, read-only or does not exist
2. When I try to compile rules.
fwb_ipt -f /root/firewallGUI/firewall.fwb -d /root/firewallGUI nessusClient
Error: Failed to start program
