  whenever i install a new system i include ufw (a firewall
program) just to catch any funny stuff that might try to
come through.

  the default settings seem to work well enough and i'm glad
i don't have to relearn the terminology and rules for iptables.

  i'm sure a much better solution is to run a separate router
as it's own layer of firewall may keep a lot of stuff out, 
but as of yet i'm just not under attack enough to make it
worth it.
