Post Untangling your network
on: August 4, 2013, 16:21

I have had an Untangle appliance for some years now, guarding my network from the internet at large. I like to share things like this 🙂

The great thing is, that there is a free version of this prebuilt security appliance that everybody can use, and it really is very easy to set up.

You can download it from here: http://www.untangle.com/ as an ISO file, that you can then burn to CD/DVD and use as installation media.

My original Untangle server was running on an HP DL360 G2, which was more than up to the job from a hardware perspective.

Originally, I used my BT firewall with the Untangle device in bridge mode, but recently I have removed the BT device since moving to BT Infifnity, since Untangle supports PPPOE.

This turned it into Router mode, and has greatly enhanced my security, since the Untangle firewall has a superior firewall to the BT device, let alone the configuration is easier and more flexible.

You can find the differences between Bridge and Router mode here: http://www.untangle.com/untangle/how-to-deploy under step 3.

Untangle also adds a whole host of other features, such as virus scanning, spam ans spyware scanners, ad blockers, so it really does give you a much better patform to control access to/from your network.

As well as recently moving to Router mode, I also retired my HP DL360 G2, on account of noise, heat and electricity consumption. It's been replaced by a laptop. Yes, you heard right, a laptop.

So, not only have I now upgraded to the 64 Bit version of Untangle, it runs very nicely on a dual core 1.8GHz laptop with 4 GB RAM, a nice side effect being the fact it now has it's own built in UPS, being a laptop 🙂

The only thing I needed was a second NIC, for which I was able to get a new Cardbus adapter off Ebay for the princely sum of £5.

The whole process was quick too. It took about an hour or so to install Untangle fresh, and then import the settings from the old server.

I really can't recommend it enough, especially if you have some spare hardware around that meets the minimum spec.

So, go and untangle yourselves folks!
