Recently I had the task of setting up a Site-to-Site IPSec tunnel between my office and one of my employees home office. At my main business HQ we have an Astaro Security Gateway running inside of a vSphere 4 cluster. However I had to find the cheapest way to get the employee hooked up.

The main tasks of the VPN endpoint at the employee’s site was:

1) Filter web, pop3, and provide security for the devices behind the ASG at the home office (1-3 computers, and other random devices)

2) Provider a Site to Site VPN connection and to allow the user access to internal resources, along with providing access to our VoIP PBX (VoIP phone at employee site)

3) Provide access to other resources such as exchange, CRM, etc… And reverse management of devices at home office from HQ

First I needed to find an affordable computer to install the Astaro Security Gateway V8 software appliance on to. My company is an HP Partner, and we love their products, so I decided to purchase a new computer that would be powerfull enough to host the ASG software, and also be protected under HP’s business warranty. I wanted the system to have enough performance that in the future, if the home office was decommisioned, we would be able to use it still as an ASG device but for something else (let’s say a real remote office).

After taking a look at our distributor to find out what was immediately available (as this was a priority), we deiced to pick up a HP Compaq 4000 Pro Small Form Factor PC. Below are the specs:

This system was spec’d very nicely for the requirements we had. Another huge bonus is that it was covered under a factory 3 year warranty from HP. Which means that if anything failed, we would have next business day replacement (I love this, and so do my clients who all purchase HP). The one downside is that the system shipped with a Windows 7 license which we wouldn’t be using, but for the price of the system, it didn’t really matter.

The system only came standard with one Gigabit NIC (Network card), however we need two since this device is acting as a firewall/router. It’s a Small Form Factor system, so we had to find a second network adapter which was compatible with the computers case form factor. The card which we purchased was:

HP – Intel Gigabit CT Desktop NIC

Part Number: FH969AA

Although the computer above is not in the compatibility list for the network card, the network card still worked perfect. Once received, we simply replace the case bracket on the card with one that shipped with it for small form factor computers.

We then burned the .ISO image of the ASG V8 software appliance, and proceeded to install it on the system. It installed (along with the 64-bit kernel) perfectly on the computer. After the install was completed, we configured it to connect to our main central Astaro Command Center and shipped the device out to the employee’s home office.

Once installed, we logged on to the Astaro Command Center user interface, and created a Site to Site IPsec using the wizard. Within 2-5 seconds the connection was established and everything was working 100%.

After using this for a few days, I checked to make sure the computer was powerful enough to be providing the services required, and it was without any problems.

Just wanted to share my experience in case anyone else is doing something similar to what I did above. If you were to reproduce this, all the hardware should be under $700.00 CAD.
