New firewall section (was: Re: HEADS UP: doc/ slush begins)

Hi Giorgos,

Thanks for your comments I have merged all of them except the few below I have 
questions about.

This does need better wording.. I can't come up with anything right now.

Well the period is at line 71, so I pushed the </para> down so I wouldn't go 
over the 72 line rule.


Also I have encountered an undefined &man.ipnat.8
