Thanks a lot! You definitly saved my computers! I can't believe that the whole time my work wasn't saved despite the iptables-save command! I really can't understand why this command is called like this!
another question: when I do
sudo iptables-save >/etc/sysconfig/iptables
I get the message
. The sudo rights seem to stop with the pipes. Isn't there a possibility to save the whole thing with sudo?
