I have a firewall set up on my laptop, as it is company policy.  FreeBSD
makes it fairly simple to set up and use with the options
in /etc/rc.conf, and I rarely have any need to tweak it.  I have a
fairly lightly modified "CLIENT" type firewall.   DHCP is an issue, but
a quick script at boot can be used to grab the dynamic IP without too
much trouble.  Otherwise I really do not have performance issues,
connectivity problems, etc, that are worth mentioning.  

I like to keep a decent eye on security, but to my knowledge I have
never run into an occasion where someone has tried to hack me into my
laptop through wireless or wired, in a way that would work.  I have
certainly seen attempted MS-Windows hacks, etc.  But nothing that would
actually effect FreeBSD.  I keep the system fairly up to date, and
rarely have any problems with security.  (The problems I have had, a
firewall would not fix anyway.)  I highly suspect that I could stop
using the firewall all together and it would not make that much of a
difference.    So do you need a firewall?  Probably not.  But since it
is really not that hard to set up and manage on FreeBSD, I would advise
anyone to use one if they can.
