UPDATE: Just before sending this email I noticed that traffic between
the two domUs starts flowing as expected only after I ping the client
from the server, however I'm still mystified as to what is really going
on.

I'm working with Justin on this and wanted to add a few details.  As he said, if you try to ping the client DomU from the gateway/firewall/router server DomU, then (after 5 or 6 seconds) the traffic will start flowing.  Only *after* doing this can the client DomU then ping the gateway (or beyond).  I'm 99.9% sure that the networking is setup correctly and *should* be working.

I believe it's a Xen or NIC kernel module problem.  We are testing a setup like it and it *seems* to work well for us on different hardware.  This box is a Dell PowerEdge with Broadcom chips (e1000).  Ever heard of this type of behavior?  Any ideas?

I just wanted to update anyone who might be wondering about this problem.  We recreated this setup on different hardware and it still does the same thing.  So, it must be in the software.  Has anyone seen this kind of thing before?  Any ideas about what might be wrong?  Thanks again.
