Sorry, this is a legitimate ICMP packet: port unreacheable. It looks like
the ftp server (ftp.freebsd.org) was making an UDP query to DNS port on
the client (which happens to have a named server running, but that's just
for the internal network, external ip address is served by an outside server)
and the client responds with port unreacheable even though there is a named
running. I'm totally confused. I'll try to find out more. By the way, if
I turn off aliasing (set alias enable off), ftp works fine again.
