Hi, I am trying to clear some of my basics. I am reading IP-Masquerading HOWTO. In it these things were mentioned, UNIVERSE="0.0.0.0/0" $IPTABLES -A INPUT -i lo -s $UNIVERSE -d $UNIVERSE -j ACCEPT What exactly does 0.0.0.0/0 mean? And why should we be concerned with it? And what is the use of rule given after it? INTNET="192.168.1.0/24" INTIP="192.168.1.1/24" The first one means the entire network of 192.168.1.x? What exactly is the second one. Does it just means 192.168.1.1 then why "/24"? And lastly, $IPTABLES -N drop-and-log-it $IPTABLES -A drop-and-log-it -j DROP Why was this rule made? And why was it "dropped"? What is the logic behind this? Shouldn't it be, $IPTABLES -P drop-and-log-it DROP Thanks a lot for the patience and bye. With warm regards, -Payal p.s please make a cc to me too. -- "Visit GNU/Linux Success Stories" www.geocities.com/rpayal99 Guest-Book Section Updated.
