While running tests in my lab, there have been a few times where I
could no longer talk out my external interface. This usually happens
after I ifconfig em0 up / down a few times to force the carp0 failover.
Previously, I have just rebooted the box since I was concentrating on
testing the pf + pfsync stuff but this time I stopped to take a look
and noticed that I am loosing a route for the locally attached network.
Is this the intended behavior?
