VMware on AWS - How to restore NSX DFW firewall rules to previous state

Image
Customers who uses NSX day-in, day-out would like to have a point-in time restore functionality of DFW firewall rules. Many customer have a large footprints in VMC and make changes to DFW quite often. This feature was missing for long time and we could see its included in recent versions . Let's see how DFW configuration roll back works  NSX DFW configuration has versioning, and it is stored in the NSX Manager.  Every time when someone update DFW configuration, NSX creates one more version but keep storing the previous ones. You can rollback for previous config but reapplying it once again.  You can find the options under Networking & Security tab , > Security > Distributed Firewall . In the right side we see an Actions drop down. Choose View to get to the below screen.  Let’s go through the use case:  1. Original state- default config with no custom rules:  a. There are no saved configurations during last 30 days: In my existing test setup, with the current setting

What is Remote Desktop?







Remote Desktop allows the graphical interface of a remote Windows system to be displayed over a network onto a local system. In addition, keyboard and mouse events on the local system are transmitted to the remote system enabling the local user to perform tasks on the remote system as if they were physically sitting at the remote system. Conversely, resources (such as printers and disk drives) on the local system can be made available to the remote system for the duration of the connection. This remote control can be established in a number of ways, including over wide area networks (WAN), local area networks (LAN) or over the internet.


In the case of Windows Server 2008, this service is provided by Terminal Services running on the remote systems and the Remote Desktop Connection (RDC) client on the local system.


Terminal Services run in two different modes, Administration and Virtual Session. Remote Desktop for Administration provides full administration functionality to the remote administrator (including access to the console session and visibility of notification messages). Remote Desktop for Administration is the equivalent to working directly at the remote system's console. In virtual session mode the user is subject to some limitations such as the ability to install applications and view console notification messages.


Windows Server 2008 imposes some administrator logon restrictions. Specifically, a maximum of two administrators may be logged on at any one time, either two logged on remotely, or one local and one remote administrator. This assumes, however, that different accounts are being used to log on. In other words, the same user may not log on locally and remotely simultaneously.
