Configuring Kemp Load Balancers for Exchange 2010 CAS Array which extends to the remote site

My example setup is as follows:

There are 2 locations connected with a direct line. The Remote location is used just for a disaster recovery and there are no users in the remote site.

There is one DAG configured which is extended to the remote site. The active databases are located in the current location and passive in the remote site. As both are in the same AD site, CAS array is extended to the remote site.

The first step is configuring the Kemp Load Balancer pair in the current location:

In this article, I am going to explain using Kemp Load Balancer HA pair in a 2 arm configuration:

Consider the names of the Load Balancers as LM1 and LM2

I am using the following Network Configuration

                        Internal   IPs                                   DMZ  IPs

LM01                10.1.1.2                                       192.168.10.11

LM02                10.1.1.3                                       192.168.10.12

Shared IP          10.1.1.1                                       192.168.10.10

Note: The shared ips are used for identifying the load balancers as pair. So in any case, if you need to specify the LM as gateway, you need to use the shared ip as gateway IP.

Power on the First Load balancer LM1 and connect the Eth0 port to any of the hub.

Connect the laptop or desktop to the same hub and assign any static ip address in the range of 192.168.1.110/111

Eth0 Port is connected to DMZ.

Eth1 port is connected to the internal network.

TO open the Kemp load balancer configuration, in the internet explorer type

https://192.168.1.100

It prompts with the user name and password.  Type the user name as bal and the password information would have been given when you purchased the load balancer

The First and foremost is to configure Ethernet ports and providing the default gateway.

Now eht0 and eth1 ports need to be configured. In the Right hand side pane, select the system Configuration as shown below

Select eth0 and specify the address below:

Specify the eth1 as follows:

By default, the management IP is configured on the eth0. But as eth0 is connected to DMZ, I would like to manage my Load balancer using Eth1.

To do that, Go to system configuration, Miscellaneous Options, and select Remote Access

Configure Local DNS Configuration:

I am not explaining you step by step here..

But the Host name I configured is LM1

I added the internal DNS server Ips in the DNS Configuration and the domain test.com.

The other important thing is configuring the default Gateway address:

The default gateway address should be the DMZ network.

You can specify the internal network additional routes in the additional routes tab.

Now you can reboot the load master by going to system administration and system Reboot.

This is the basic configuration required before you start with configuring CAS Array Virtual Services.

How to create Disclaimers for outgoing messages in Exchange 2010

Creating Disclaimers for outgoing messages in Exchange 2010

1.       Logon to any one of the Exchange 2010 server and Expand Organization Configuration.

2.       Select Hub  Transport as shown in the picture:

3.       In the right-hand pane, select “ New Transport Rule”

4.       In the Name Window, type the name as  “Disclaimer for outgoing e-mail” and click on next.

5.       Next window is “Conditions”. You can select from People and you can add all the people or you can select many different options. But I am going to use the checkbox “From a member of Distribution List” and going to add the distribution group.

To add the Distribution list, click on the distribution list and add the group as required.

6.       In the actions tab, Select “append disclaimer text and fallback to action if unable to apply”

                 Below select the disclaimer text and add the disclaimer text as per your organization.

                 Sample of the disclaimer text:                 

“If you are not the intended recipient of this email, or if you have otherwise received any of this information in error, please notify the sender immediately and then delete from your system all copies of this email and any attachments”

7.       In the next window, you can add the exceptions if required if you do not want to send for specific users.

Click on next and click on new.

The Disclaimers Transport rule is created and every user who is the member of that group sends the e-mail outside will get the disclaimer at the end of the text.

If you would like to edit the rule, you can right-click the rule and click on “Edit Rule” and can make changes as required.
