SRG-OS-000145-ESXI5 - The system must be configured with a default gateway for IPv4 if the system uses IPv4, unless the system is a router.

Information

If a system has no default gateway defined, the system is at increased risk of man-in-the-middle, monitoring, and Denial-of-Service attacks.

Solution

From the vSphere Client/vCenter, click on the Configuration tab; click on DNS and Routing; click on Properties/DNS and Routing, Configuration/Routing. Add a default gateway (IP address is required). Click 'OK'
