Hi,
  I'm not new to linux but I'm needed to administer a small group of
computers snce recently and need to add a firewall to the network. It's
a windows lan. I have been reading iptables howto and tutorials since
many days but it's not very clear to me how to make my own firewall.
What to add for a windows lan etc.

Can someone point me to some guide/website that would help me learn
iptables quickly and easily? Maybe I need to read more howtos for
detailed security later but for now I need urgent help or I won't be
spared.

Regards,
Froogle
