Hmm... your problems seem to be with the MTU on the PPP link, wich
shouldn't be an issue with this setup, since both the relevant interfaces
are ethernet and have the same MTU. It does seem that in your case ipnat
should be changing the MTU for the packets from the iMac to something more
appropriate for ppp. I wonder if using OT Advanced Tuner
<http://www.sustworks.com> to adjust the MTU on the mac would help (it
would probably affect local performance however).

Well...hope any of this screed helps
