Few questions about iptables
Could someone clarify few things considering iptables..
1. I have made script for setting few options for iptables.
What is best way to get those options running on each startup?
Do i need to set that script executed on each start or is there some other ways to do that?
2. Can i "easily" configure my existing iptable with firewall builder (fwbuilder)
or is there some more suitable program for that?
3. If i want to return my default Arch setting for security, is it so simple as removing iptables?
In this kind of situtation i don't want to leave any open holes with my iptable practise.
Hopefully i can get some nice firewall running. 
Lets add that my computers are just normal desktop/netbook with KDE on both.

There's no such thing as a stupid question, but there sure are a lot of inquisitive idiots !

Re: Few questions about iptables
Thats mostly for creating script/options..
Is that IPTABLES_CONF=/etc/iptables/iptables.rules right plase to put my configurations??
What about questions 2 and 3 ??
If someone have experience with fwbuilder and returning defaults after uninstalling iptables i would appreciate some information about those.

Re: Few questions about iptables
Ok
One thing that i didn't notice was using iptables-save.
That was my key to get iptables working properly.
But no luck yet with integrating iptables and firewall builder.
At least i got somekind of firewall up and running. It's good place to start.

Use `/etc/rc.d/iptables save` and add 'iptables' to your DAEMONS array in rc.conf
This will save your rules to /etc/iptables/iptables.rules and load then at boot time.
3. If i want to return my default Arch setting for security, is it so simple as removing iptables?
In this kind of situtation i don't want to leave any open holes with my iptable practise.
Running `/etc/rc.d/iptables stop` will remove all rules you've made.

Re: Few questions about iptables
Thank you fukawi2
It's nice to know that it's possible to get everything back to normal, if something goes wrong.
Somehow i found firewall builder quite hard to use for this, so maybe it's just better stick with pure iptables and learn how to use them properly.

That's my preference, which is why I couldn't answer question 2 for you
