The other day I setup a virtual machine running under Hyper-V. If you are not familiar with this OS – let me be lazy and quote: SmoothWall is a Linux distribution designed to be used as an open source firewall. Designed for ease of use, SmoothWall is configured via a web-based GUI, and requires little or no knowledge of Linux to install or use. I wanted to play around with it to see if I could set it up as a filtering proxy; so I downloaded the and tried to install it in a Hyper-V virtual machine. I created a virtual machine with 512MB RAM, a 127GB dynamically expanding virtual hard disk, 1 CPU and two legacy network adapters connected to different networks. For the most part, it “just worked”. The installation was a very traditional Linux installation process (contrary to the Wikipedia quote above) and I only encountered two hiccups:.
It did not detect my network adapters by default – and did not tell me that I had to go and kick the network detection routine. This lead to some confusion where I was trying to configure my public / private interfaces and it believed that it had no network adapters.
Mystery of your fridge's strange NOISES solved: Scientists finally figure out why it makes such a racket at night. Anyone who has walked into their kitchen at night will have heard it - a series of strange pops and cracks emanating from the refrigerator. Loud cracking noises are. Crack sounds from refrigerator.
At first the system was failing to get a DHCP address from my DHCP server. On a hunch I checked the option to Enable spoofing of MAC addresses on the network adapters – as shown here: Which seemed to solve the problem.
However I was able to go back the following day and uncheck this option and have the system work correctly. I am not sure what really happened with that. But I now have it up and running perfectly: And it is functioning as a filtering proxy.
Now I just have to wade through mountains of configuration files to actually get it to filter the right things 🙂 Cheers, Ben.
How To Install Smoothwall Express 3.1 Pro
First of all, you need the following: -a spare PC or an old server you don't use anymore, with a working CD-ROM drive -two or more NICs -the SmoothWall Express.ISO burnt to a bootable CD-ROM Then just install the SmoothWall OS onto this PC or server. Follow the instructions provided during installation. Set up a Red interface for your external connection to your ISP, Green interface for your internal network, a Purple network if you want to attach a wireless LAN, and an Orange network if you want to attach a DMZ. (you need separate NICs for each of these). It's been a while since I installed the SmoothWall OS on a PC so forgive me for not remembering all the details.

I'm fairly certain that the installation wizard will guide you through the configuration smoothly, though.
