[plug] Examples of 'dpkg --get-selection > list.txt' for firewall

[Daniel]

Hello Plug,
on Debian Woody 
looking at the Firewall as the smallest install and most important with
no-X and running iptables ....

If I run 
dpkg --get-selection > packagesinstalled.txt

Is there somewhere I can examples of classic package selections for
firewalls on the net so I can look through to see if any of my packages
stand out as unnecessary?

Thanks very much,
Daniel.
