Looking for an editable script

[Madison Kelly <linux@alteeve.com>]

Hi all,

   I am trying to build a script to serve my office network. To date I 
have used Monmotha's Firewall script but I need more than it provides. I 
have been trying to hack his excellent script to fit my needs but a 
programmer I am not! :)

   I need something I can work into doing the following;

- Allow limited TCP/UDP ports into the firewall/router (easy enough)
- Allow limited TCP/UDP ports into LAN clients (common list for all LAN 
clients)
- NAT clients that will be public and for each client allow a specific 
list of inbound TCP/UDP ports and where the clients will, internally, 
have their own subnet seperate from the LAN clients.

   I am not asking anyone to do my work, but a head start would be 
greatly appreciated! In the meantime, back to trying to bang Monmotha's 
script to suite (please save me!) ;)
