Xen users - Apr 2010 - switching from bridge to nat on existing domU

Hi,

My current domU config.sxp uses the /etc/xen/scripts/vif-bridge script

I see a vif-nat script and would like my domU to use it.

I changed my config.sxp as follows;

(device
         (vif
             (bridge bond0)
             (mac 00:16:3e:3d:e0:e6)
             (script /etc/xen/scripts/vif-bridge)
             (uuid 8b3535c4-25e5-521c-e495-27f956b99fb8)
             (backend 0)
         )
)

to

(device
         (vif
             (bridge bond0)
             (mac 00:16:3e:3d:e0:e6)
             (script /etc/xen/scripts/vif-nat)
             (uuid 8b3535c4-25e5-521c-e495-27f956b99fb8)
             (backend 0)
         )
)

My Running Xen book has an example (unsure if it applies to Xen 3.4.2  
which I''m running) of also adding;

vif = [ ''ip = 10.0.10.200'', ]
NETMASK="255.255.0.0"
GATEWAY="10.0.10.1"

So would my config look like this;

(device
         (vif
             (bridge bond0)
             (mac 00:16:3e:3d:e0:e6)
             (script /etc/xen/scripts/vif-nat)
	    (vif = [ ''ip = 10.0.10.200'', ])
	    (NETMASK="255.255.0.0")
	    (GATEWAY="10.0.10.1")
             (uuid 8b3535c4-25e5-521c-e495-27f956b99fb8)
             (backend 0)
         )
)


Would this then be the ip addy of my domU?

And how would I get it to like like 10.10.10.200 with a gateway of  
10.10.10.1, same subnet mask?

Basically, I would like my domU to think its still 10.0.10.200 but the  
world to think its 10.10.10.200, just a NAT.

Unsure how to do this in Xen, I''ve done it in VMWare but via a GUI.
