Here is one place it would:

I setup a gentoo install inside a vmware on windows to use as the
recipient of dmz traffic from an upstream (hadware) router.

This was simply to play around with the traffic being aimed from the
internet at my IP address.  I wanted to study what was being dropped.

A firewall would be essential there.
 1. to log stuff for study
 2. to keep from
    getting rooted by some smart bad guy.
