sysctl -w net.inet.ip.forwarding=3D1 should be plenty enough.  After that,
it really depends on the topology of your network.

FWIW, this afternoon when I could take a try at booting a domU, I used a
modified vif-bridge script to do bridging by doing this:

vif =3D [ 'mac=3Dlalala, bridge=3Dbridge:bridge0:fxp0' ]

The meaning of the bridge parameter is the following:  first it starts
with bridge to distinguish between plain ifconfig case and bridge case,
then it bridges the vif interface with fxp0 on bridge0, creating it if
necessary.  I'll send it tomorrow if you want.

BTW, xentools20 package needs some work (and should include such a
script).  Also, it really needs to default to 127.0.0.1 for the relevant
daemonized parts, I've patched mine for that.  I'll have a closer look
at this during the next few days.
