Hmm.. thats strange, since I did nothing special.

Here once more what I did, maybe (hopefully) we misunderstood:

eth0 has my internet ip address.

I used the network-bridge-script to setup the (xen-) networking,
set up ip 192.168.37.254 on xenbr0.
Then I startet domU.
After that I added masquerading to eth0.

I have the following interfaces in the bridge: peth0, vif0.0, vif1.0

I'm using debian sarge as os. Maybe they set something special in their
networking-scripts?

It is a test-machine, so i can give you the root-pw, if nothing helps.
