Some feeback on my netfilter script wanted :-)

[arkaine]

I've been looking more into iptables and netfilter recently.. and i figured a nice way
to learn, is to try everything.. Though writing a bash script to do all this is a
very complex way of doing it, it's a nice way to learn and help others learn..

It works just fine as it is, although i'm always chaning/adding features. Posted it here
to get feedback from people with more experience or tips on things that might
be done better (and don't whine about how hard i'm doing this, because i already know)

Anyways, thanks for any reply
