It pretty much needs to be your decision;  Each component in your
network has an effect on the overall security of your machines (and
data).  The way I look at it is that the router is pretty much the
front door, I'd rather keep it locked.  Lotsa bad guys out there.  :(

After I finally started getting a handle on linux and got a my first
good and solid machine built I got hacked through an open ftp port
(highspeed timer exploit).  The only thing that saved the now
installed rootkit from sending reams and _reams_ of information about
my machine to a hotmail address was that I hadn't configured sendmail
yet.  Lol.  (That was the day I fell in love with sendmail.)

Anyway, I found out about it (root got the email) and decided it was
time for me to learn something about security.

In the meantime, and mad as h***, I sent a relatively polite email to
the hotmail address - curious how it was done.  Took me a while to
find out because the next day my linux wouldn't boot.  At all.

Now I try to lock things down.  I lost months and months of work to
that incident.
