This will happen if you have a public static ip address on your freebsd
box, connected to an adsl router but the adsl router's lan interface is
on a different network. This situation primarily occurs when you turn
an adsl router into an adsl modem, e.g.  you enable ppp half-bridge mode.

 I pipe those, and other messages to a virtual terminal, like this:

syslog.conf
--
*.err;kern.debug;auth.notice            /dev/ttyv3
