Problem

I tried to create a new domain controller in an existing forest but I kept receiving the following error:

Solution

Make sure that the user you are using is a member of Enterprise Admin group. Mine didn’t 🙂

Once I added the user I was using into Enterprise Admin group the problem has been solved.

After a very long time of endless researches on the internet with “0” examples and explanations of WAN simulation in VMware we decided to write this “Bible” on how to implement WAN solution in your VMware environment. Hoping it will help you and save you a lot of testing time. Enjoy!

WAN Configuration

1.   WAN Prerequisite in vCenter

On one of our ESX servers we created two additional virtual switches.

  • Vswitch2

             1.With one Virtual port group by the name : LAN 4 WAN

             2.This virtual switch does not connect to any physical network adapter.

             3.Promiscuous mode is enabled on both virtual switch and virtual port

                 group.

  • Vswitch3

             1.With one Virtual port group by the name : WAN

             2.This virtual switch connects to a physical network adapter: vmnicX

             3.Promiscuous mode is enabled on both virtual switch and virtual port

                 group.

2.   Creating Monowall Virtual Machine

             1.We created a virtual machine by the name: m0n0wall.

             2.The SPEC that we used for the monowall server is as follow: 256MB RAM,

               two network adapters: LAN 4 WAN and WAN, Hard disk: 8GB   

3.   M0n0wall Installation

             1.Make sure that the m0n0wall in on the proper ESX server and that the

               DRS Rules don’t apply to it.

             2.Make sure that the m0n0wall server has two network adapters, the first

               must be connected to “LAN 4 WAN” virtual port group and the second

               must be connected to “WAN” virtual port group. As shown below:

          

             3.Force the m0n0wall virtual machine to start from BIOS

             4.Power on the virtual machine, go to startup and change the order of the

               startup (cdrom first, Removable devices second.)

             5.Save the changes and exit.

             6.Power off the virtual machine.

             7.Connect the iso file into the machine’s virtual cdrom.

             8.Power on the virtual machine.

             9.During the first startup the following message will appear:

        

             10.After the machine had powered on, connect the floppy file into your

                computer, and afterwards connect the virtual machine’s floppy to it.

             11.Reboot the system (option 5)

             12.After the server has started, define the intrefaces as LAN >> lnc0 ,

                WAN >>  lnc1 , and reboot the server and set the LAN IP to :

                192.168.1.2

             13.After the server has started, if you will see the following, it means that

                the operation has ended successfully. In addition, make sure that the

                message from paragraph 9 doesn’t appear during startup.

              

             14.Choose to install the OS from hard drive.

               

             15.After it successfully finished, disconnect the floppy drive from

                the virtual machine.              

4.   Configuring LAN Clients

             1.Make sure that the LAN client is on the proper ESX server and that the

               DRS Rules don’t apply to it.

             2.Make sure that the LAN Client has one network adapter, connected to

               “LAN 4 WAN” virtual port group.

             3.Make sure that the IP of the LAN Client is within the range of:

               192.168.1.X-192.168.1.X (that you defined)

             4.Make sure that you can ping to the m0nowall server (192.168.1.2)

             5.Make sure that you can ping to your network subnets.

             6.Repeat paragraph 1-5 for every LAN client in your system.   

5.   M0n0wall First Configuration

M0n0wall First Configuration:

            1.Connect to one of your LAN clients.

            2.Open internet explorer and go to : http://192.168.1.2         

            3.Login with the following credentials : admin (mono)

            4.Make sure that the m0n0wall interfaces are as follow: 

              – LAN

              

              – WAN

               

            5.Go to m0n0wall firewall > Traffic Shaper pipe and create a new pipe.

            6.Make sure that the m0n0wall firewall > Traffic Shaper rules are as follow:

             

6.  Configuring WAN Clients

            1.Make sure that the WAN client is on the proper ESX server  and that the

              DRS Rules don’t apply to it.

            2.Make sure that the WAN client has one network adapter, connected to

               “WAN” virtual port group.

            3.Give the WAN client a static IP address.

            4.Set the WAN client’s default gateway as the IP of the WAN interface

              in the m0n0wall server

            5.Make sure that you can ping to the m0nowall server (192.168.1.2)

            6.Make sure that you can ping to your network subnets.

            7.Repeat paragraph 1-6 for every WAN client in your system.
