Bryan,
The devil was in the details, particularly the fact that your
external interfac uses an RFC 1918 address...

Notice the rule that was hit: "Shorewall:man1918". Do you have
the "norfc1918" option set for eth0 in /etc/shorewall/interfaces ?
E.g.:
net eth0 detect dhcp,routefilter,norfc1918
^^^^^^^^^
which is the Bering 1.0-stable default I believe.
