I am sitting on a DHCP connection at home.
I decided to turn log_in_vain on.  I figured I 
would just see what would happen.  
To my surprise, I actully
am getting people trying to connect to my 
box. Since I have no idea why folks are doing
this, I am assuming mistakes, I would like to
set up a firewall for safety.  I have read articles saying
to enable natd and the FreeBSD OS firewall.  I only have
one machine and dont need any address
translation.  Is there a way to enable the 
OS firewall and have a dynamic IP without using natd? 
Should I use a diff firewall from the ports?  Is it common
to have a firewall on a home computer attached
to a cable modem?
