I get quite a number of these in my firewall log:

It is coming from my router to my desktop, but what is it about?
ICMP type 3 code 0 == Network unreachable error.
Ok, so the router is telling me that the netowkr was unreacheable, perhaps when attempting to send the package in brackets, that one to "80.58.61.250"? If that is an information the router is sending me, should not those packages be allowed? If so, how? - -- Cheers, Carlos E. R.
