Hello Bret,
I don't see anything wrong in your bpf configuration. Maybe you can
turn on promiscuous mode and copyall mode on your fta0 manually.
I think dhcpd daemon does this at startup automaticaly, so turning it on
manually
would not probably help.
I haven't mentioned I had applied fddi patch. I've found this patch
in some posting in this mailing list. I don't remember URL nor author of
this patch.
Try to search archives if you want know him.
I've had also problems with some dhcp clients on ethernet being served
by
alpha server on FDDI. After adding three lines to common/packet.c it
started to work.
I don't know if it is bug in dhcpd or misconfiguration of our
FDDI<->Ethernet bridge.
This is all I know, bellow are the patches. Hope it will help you.

BOTH PATCHES ARE FOR 2.0b1pl6.
patch 2 (FDDI<->Ethernet problem)
-------------------------------------------------------------------------------
For version 2.0b1pl6:
add these 3 lines under line 167 in file common/packet.c AFTER
applying patch 1.
lh.llc_un.type_snap.org_code[0] = (u_char)0x00;
lh.llc_un.type_snap.org_code[1] = (u_char)0x00;
lh.llc_un.type_snap.org_code[2] = (u_char)0x00;
For version different from 2.0b1pl6 try this:
In function assemble_hw_header, section for FDDI, fill
lh.llc_un.type_snap.org_code[3] with 0x00,
(put it under line "lh.llc_un.type_snap.control = LLC_UI; /* 0x03 */"
)
patch 1 (support for FDDI)
