The other machines are bsd routers and windows boxes, all communicate fine
before I boot into xen, but not after. The problem clearly lies on the xen box.

Once I boot into xen I cannot access anything to or from my xen machine. It
cant ping anything, and nothing can ping it for example.

When booted into CentOS (with everything fine) its 2.6.18-53.1.4.el5.
When booted into Xen, its 2.6.18-53.1.4.el5xen.
It seems I can reproduce this in Fedora Core 8 as well. I get the same behavior!
Thanks,
