Share network connection via management port? [closed]

I'm running Ubuntu Server 14.04 on a Gen6 HP Proliant ml110. Is it possible to share an internet connection through the iLO's management NIC port?

That is, would it be possible for a computer connected to the management port to share an upstream Internet connection?

And how would I do this on Ubuntu 14.04 server?

TL;DR: No, it doesn't work that way.

On Gen6, HP was shipping iLO v2.

The HPiLO2 User Guide is available from HP here as a PDF.

While the iLO is able to inspect and monitor the server, it is not possible for the OS on the server to use the iLO's NIC as it's own - they are functionally separate devices. The manual does not describe a way for you to use the iLO as an additional network interface accessible to the OS, which is what would be necessary for you to share an Internet connection in the way that you describe.

Indeed, at the bottom of p62, into p63 is this sentence:

You can only use the iLO 2 Shared Network Port and the iLO 2 Dedicated Management NIC port for iLO 2 server management.

This confirms that, no, you cannot configure the Management NIC the way that you describe.
