Networking :: Iptables (and starting it)

Hi all
again with pointless question

now i'm setting an iptables on my dsl-n frugal installed system to block viewing some url (like "parental control"...)
i found iptables.dsl on dsl repositories
i downloaded it and put on /mydsl folder (same one where i put all .dsl extension i whanna autoload at startup)
rebooted

it says loaded iptables at startup

but
a) there is no /etc/sysconfig/iptables file
i created one by myself, from scratch (well, copying one from google )

b) there is no "/etc/init.d/iptables" script to start|stop|reload
so how can i start/stop/reload iptables?

c) i tried to launch
# iptables -L
but this is the answer:

Code Sample

FATAL: Module ip_tables not found. iptables v1.2.6a: can't initialize iptables table `filter': iptables who? (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded.

someone can point me where am i wrong?
(assuming i'm not really competent with linux nor iptables )

Iptables does compile quite easily.

To start it, most prefer creating their own script and running that from bootlocal.sh, /etc/sysconfig/iptables is a distro-specific way. Or most download the nice linux firewall script courtesy of projectfiles.com and then start that from bootlocal.sh

You can block sites without iptables, too:
Just add the url(s) of the site to /etc/hosts with an ip of 127.0.0.1, so they all point to yourself and unless you are running a web server, no getting to those pages.
