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.
