Thanks for the suggestion, but it simply doesn't work.  I get no 
on-line light on either end of the cable that goes from WAN on the box 
in question to LAN side of my router.    status.php says no carrier on 
that interface.

My router is m0n0 on a soekris 4501, and the box that I'm trying to set 
up as a bridge is m0n0 on a soekris 4801.  (I'm testing setting up a

Good point.  I could always put use an NTP server that would be 
reachable over the LAN (admin) interface.

The cables I've been trying with are NOT cross-over, but my 
understanding is that the soekrises do automatic MDI/MDI-X detection.

The one thing I haven't done is simply test the 4801 in a normal 
configuration.  So what I will do is put the uninteresting router 
config on the 4801 and see if it works ... Yup.  It works with a 
"normal" configuration so there isn't anything obviously wrong with the 

I don't actually need to set up a transparent bridge, but it would be 
very very convenient.
