Hi!

Thanks for your responses!
Both answers were very helpfull.

Everything worked just great: VPN, the nat and the VM LAN.

My mistake was that in the interfaces file I was always declaring both
the eth0 and the xenbr0 (even with the eth0 with no configurations).

Now I just have another question. Assume I'm going to create a new VM,
and it will have the same parameters as this one (bridge eth0). I
should create another bridge (xenbr1), or it will automatically use
the existing bridge (xenbr0)?

Also, I'm trying to install windows server 2008 instead of the xp. I
get a blue screen with the 0x0...7E error. I've checked the list for
previous errors like this, and trying the following.
 - Used 2 different isos (one downloaded from MS) and another from a DVD.
   - with the DVD iso I get the blue screen just after the "windows
loading files"
   - with the MS iso I get the blue screen a few seconds after the GUI
is launched saying "starting windows"
- I've changed the DVD configuration file from file:/ to tap:aio:
- I've all acpi,apic and pae = 1 in the config

Any ideas? Should I send another email with a different subject?

Thanks again for your suggestions.
Vinicius
