|How is the gateway configured?

gateway works just fine, it routes my 192.168.200.0/24 to 10.0.0.1 (a
linksys route, hooked up to the cable modem)

|^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

everything has worked 100% reliable, and beyond the bridge everything
(bedides my laptop) seems fine.  It may have very well been a 'windoze'
thing on the laptop, I'm not sure.  

Well, I sat down today on the laptop, everything was working.  I turned
off spanning tree to cut down some of the traffic.  I restarted my
networking, things worked... I walked away again, and when I came back
lo-and-behold things were not working.  I dunno, maybe I'm going crazy...
I'm trying to get some standard base to work with... and just hopefully it
will keep working.  I let you know if I discover any more problems.
thanks.
