I've got a runnig xen host with "nothing" inside dom0 and some domU

1. domU: firewall and router (external and internal interface)
2. domU: webserver with bind (internal interface)
3. domU: mailserver (internal interface)

if I start a query at the domU bind from the inside of the network it
works,
if I start the same query from the outside of the network then it
fails.
I'm sure that the firewall allowed this query, I'm using the same
iptables rules which worked on the 3 differnt real boxes.

Does anybody knows this problem?

I had problems with bind in domU until I arranged for the following to
be
executed in the domU when interface 'eth0' was brought up:

ethtool -K eth0 tx off

Before I applied that change, tcpdump showed that UDP packets from the
domU
had invalid checksums.

Great this solved my problem, lot of thanks
Daniel
