If anyone is interested, we found it.  Our gateway router had filters on 
it to allow 80, 443, 21, 22...and then deny everything else.  We added an 
allow for dhcp, and wallah, everything is working.  What still has us 
scratching our heads, and why we kept ruling that out, is even with the 
filter in place, dhcp still worked, as long as the client dind't have the 
broadcast flag set.  Makes no sense to me, either dhcp is blocked or it 
isn't I would think, reguardless of broadcast client flag.  Thanks to all.
