No; you're on the Internet and thus will be receiving random crap
traffic all the time. Maybe it would be nice to know what sort of
traffic it is though, as opposed to just source and dest.

Well the alert is next to useless in terms of information provided
so I wouldn't say it's doing its job.. A Linux firewall in the
middle might be more enlightening, but if you're not bothered then
ignoring these is probably harmless also. :)

Cheers,
