[Xen-users] 3.0.2 NAT headaches

["John Wells" <groups@xxxxxxxxxxxxxxxxxxxxx>]

Guys,

I'm struggling to make NAT work on Debian Sarge. Bridging works fine, but
when I try to switch to NAT, I can't ping anything.

Here is what I have done:

Switch /etc/xen/xend-config.sxp network-script and vif-script from
network-route and vif-route to:

(network-script network-nat)
(vif-script vif-nat)

In my domU config:
vif=[ 'ip=10.0.0.1' ]
dhcp="off"
hostname="vm01.example.com"
ip="10.0.0.1"
netmask="255.0.0.0"
gateway="10.0.0.254"
extra="3"

When I boot the domU, I set eth0 to be 10.0.0.1/8 and the default route as
10.0.0.254. I cannot ping out at all.

When I look at dom0 after booting the domU, I see the following interfaces:

Can anyone tell me what I'm missing/doing wrong? I really appreciate any
help you may provide.

Thanks!

John
