I have just installed Debian 7.0.0 and have used
sudo iptables-restore <saved.iptables
to reload my old iptables.
My question is, do you acually have to start or enable iptables (as with "ufw enable") or is it always running? I tried
peter@app-server:~$ sudo iptables -h | grep start
peter@app-server:~$ sudo iptables -h | grep enable
and, as indicated, I got no results.
