OK, I setup 2 boxes on either end of a RELENG_7 box from about May 7th
just now, to see with 2 boxes blasting across it how it would work.
*However*, this is with no firewall loaded and, I must enable ip fast
forwarding. Without that enabled, the box just falls over.
even at 20Kpps, I start seeing all sorts of messages spewing to route -n

Mike,
Is the monitor running on the 7.0 box in the middle you are testing?
I set up the same configuration, and even with almost no load (< 1Kpps)
can replicate these error messages by making the remote IP address (in
your case 'default', disappear (ie: unplug the cable, DDoS etc).
...to further, I can even replicate the problem at a single packet per
second by trying to ping an IP address that I know for fact that the
router can not get to.
Do you see these error messages if you set up a loopback address with an
IP on the router, and effectively chop your test environment in half? In
your case, can the router in the middle actually get to a default
gateway for external addresses (when I perform the test, your 'default'
is substituted with the IP I am trying to reach, so I am only assuming
that 'default' is implying default gateway).
