other than the Workstation, VMware ESXi does not has the functionality to “NATting” virtual machines network traffic into a public network.
My approach to implement NAT is a virtual machine with a slimmed-down (Debian) Linux.
These virtual machine has two network interfaces. The first interface is connected to a vSwitch called “Public LAN” with access to the public LAN, the second interface is connected to a vSwitch which has no physical adapter attached to and is called “NAT Network”. On the NAT interface a DHCP server is assigning IP Addresses.
since Windows 8 respectively Server 2012 the policy to install Updates at a specific date and time has no affect.
Microsoft changed the behaviour for installing updates. The schedule for a installation and restart of updates is just defined by the deadline for Updates on the WSUS Server.
here is a short tutorial to check a webserver with nmap.
Update to the latest version of nmap. Otherwise nmap would not work (Error message:/usr/bin/../share/nmap/scripts/ssl-heartbleed.nse:40: This script requires the tls.lua library….). For example debian wheezy. Add the backport repository “deb http://ftp.uni-erlangen.de/debian/ wheezy-backports main” to /etc/apt/sources.list.
root@debdev:/# apt-get update
Install the latest nmap version
