[ross817]

I don't really see a a point to setting iptables to a variable. Would it really be so hard to run a perlexp like "s/iptables/sbin\/iptables/g"?

[jimmayl1]

Haha, love seeing brainfuck.



[lonniebiz]

You never mentioned, so far, how to make this script run on machine startup.

Awesome tutorial!

manageability. Think if chains as functions.

[thablackmarkit]

Whats the advantage of branching to a custom chain vs keeping the rules in INPUT ?

[GegoXaren]

well, i think that GNU/Linux and most modern UNIX OS:s hase some caind of iptabels..

so Windows is screwed...

[RebelFleetCommander]

This is nice. Thanks!

[eliden]
