Xenserver 7.2 configuration - Power Edge T320

Hi.

I have a Power Edge T320 server, with Xenserver 7.2, an off board network card with 4 inputs and an onboard card with 2 inputs.

All are working. I tested them all. I created a repository and installed the Virtual Machine (Debian 7.2).

The problem is that I can't serve the internet.

Any suggestion?

Thank you all for your attention.
