[Xen-users] Dom0 cannot see network when bridge is enabled

I've seen a lot of threads w/ similar problems, but none have posted a

I am using Debian 4.0r1 (Etch). I was using the xen packages from
stable, but have tried w/ testing as well and the problem persists.


Host is on network

Dom0 is thus

DomU is

When the bridge is enabled, DomU can ping everything. Everything can
ping DomU.

Dom0 can only ping DomU and itself. It can't see the network
or anything beyond.

tcpdumps have not shown any ICMP traffic on any of the interfaces I can
see from within the Dom0, and machines in being pinged from
the Dom0 see nothing either.

I'm trying to work out how it's supposed to work. It looks like the
bridge works by binding all the interfaces together via a common mac
address, is this correct?

How then, do peth0 and eth0 see each other's traffic?
