[Lab] Simple ISA Server 2006 setup in VirtualBox

I’ve just installed and configured Microsoft ISA 2006 server in Windows Server 2003 in VirtualBox. The topology is as follow:

Installation of Windows Server 2003 and ISA Server 2006 are quite straight forward.  If you have experience installing any Microsoft Operating system and know how to install software, you should not experience any issue here.

I’ve found a number of very good tutorial below even for beginner as screenshot is provided with explanation.

Once the installation completed, I’ve performed ping test to both interfaces in ISA Server to make sure the client can communicate well with Windows Server 2003.

However, I was unable to ping them once ISA installation has completed. This is because ISA will block all ICMP traffic by default.

How to enable ping in ISA Server 2006?

I’ve found a good tutorial here written by Tarek Majdalani. It’s easy to understand with screenshot as well. Thanks Tarek 🙂

PROBLEM

Currently I’m able to ping from Client to internal interface of the ISA, but still having a problem to ping to the external.
