Connecting to iDRAC VPN by using L2TP over IPsec on Ubuntu Linux 18.04

The integrated out-of-band management platform on Dell servers is called iDRAC. By default, our clients can access iDRAC interface on their servers only by connecting to a VPN. A client can also allow temporary access to the iDRAC of a specific server from the Internet, i.e., without the need for the use of a VPN. Once enabled in the Customer Portal, public access will stay enabled for the next 24 hours, and it can be turned off ahead of schedule.

Credentials and instructions on setting up a VPN connection to the OoB network are available to our clients in the "Profile > Account" section of the Customer Portal. iDRAC credentials for each server can be found on a server's details page in the Customer Portal.

This article will guide you through the steps required to set up an L2TP over IPsec connection to our VPN gateway.
