Fair enough; however, I have turned on and off all options I can find on the 
router related to that sort of thing and nothing changes.  More importantly, 
I can do this:

root at george:~# ping -f tobeys.gotdns.com
PING tobeys.gotdns.com ( 56(84) bytes of data.
--- tobeys.gotdns.com ping statistics ---
3609 packets transmitted, 3570 received, 1% packet loss, time 47185ms
rtt min/avg/max/mdev = 23.229/31.162/72.274/7.039 ms, pipe 6, ipg/ewma 
13.078/27.893 ms

Clearly, there is no packet rate limiting in effect here...
