[Xen-users] domU NAT network cannot connect

[Xi Shen <davidshen84@xxxxxxxxx>]

Hi,

I followed this guide, and started myÂxend service with nat-network support:

(network-script network-nat)

(vif-script   vif-nat)

Then I started my domU with the following vif configure:

vif = ['ip=10.0.0.1' ]

my domU is a win7 system, and I configured the network as:

ip: 10.0.0.1

netmask: 255.255.255.0

default gateway: 10.0.0.254

dns: 8.8.8.8

I added the iptables NAT rule:

> iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

But my domU still cannot connect to the network.

On my dom0, "ifconfig -a" returns as follow: (note: I started the vif8.0 IF by manual)

I am new to xen, so I might have missed some settings. Please be kind to point out.

Thank you.
