how iptables masquerade works
Hi, I have setup my linux box for masquerading following IP masquerading instructions (http://tldp.org/HOWTO/IP-Masquerade-HOWTO/). When the machine starts up the scripts with the rules runs, but I don't see IPTABLES running as a daemon. Can someone kindly explain how masquerade works and if IPTABLES is not running, how does the rules get applied? does iptables runs once to put the rules in kernel? another question is why would you run iptables as a daemon?
