In an earlier post I went through the process of coming up with a solution to be able to test an Exchange 2003 to Exchange 2010 migration using VMs. In order to simulate a multi-site AD environment I wanted to use Vyatta based routers to create my network infrastructure. In this post I’ll actually walk through the process of setting up the ESX and theinternal router. In the next post(s) I’ll go into configuring the DMZ and internet routers and firewalls. As a reminder the environment I want to set up will look like this…
.
In order to actually be able to implement this I first had to go configure the appropriate networking configuration on each of the ESXi hosts.
First I needed to create a virtual switch utilizing the NIC attached to the crossover cable. This is done by going to the “Configuration” tab for the ESX host within the vSphere Client.
Clicking the “Add Networking” option will walk one through the wizard to configure the new switch. I started by choosing “Virtual Machine” on the Connection Type Screen.
On the next page I choose to create a new virtual switch and pick the appropriate physical NIC that will be used to communicate with the other host. (If I had the capacity to put all the VMs one one host I could create the vSwitch without having to specify a network adapter)
Then I created an initial Port Group and specified a VLAN ID for it. In this case for the Remote Site (192.168.3.X/24) I’m specifying VLAN ID 23.
Once completed the new virtual switch should look similar to the one shown below.
Now that the vSwitch has been created, I can add port groups for the other networks: DMZ (192.168.254.X), Internet (10.0.0.X) and HQ(192.168.2.X). Each one of these should have a unique VLAN ID associated with it which is also used when these port groups get created on the second host.
