LOL, no, I have it setup per the documentation on Server NATs, which
is what I need.  A filtering bridge is more of a 1:1 setup, and I
don't have that many IP's available

Its acting like a bug, that's why I was asking if anyone else is using
it on 1.3

The next chance I get to travel down to the colo, I'll have 1.2 loaded
on a flash card to test it out.

not had to use proxy arp, server nat, or 1:1 nat. I simply setup the box to be a filtering bridge
(Option checked in Advanced-->Enable Filtering Bridge). Then, I simply add rules to allow traffic
through (with default deny rule of course).
