QoS for the small office or home office (SOHO) does not need to be a wish list item any longer. I've mentioned the Untangle open source gateway on this blog before, and I keep finding good nuggets of functionality that make a strong case for the product. The Untangle's QoS feature is simple, yet effective. There are two main categores for the QoS management, the first being upload and download allowance. The second are port and host rules that can be carved out for specific systems and their applications. Figure A shows the main QoS configuration page on the Untangle gateway.
Within the QoS management page, a QoS rule can be added with ten or more rules that can be applied in successive criteria ("and"). For example, a QoS rule can be added to give a Web server priority. This example Web server runs ports 80 and 443 and exists as 10.187.187.106 on the internal network of the Untangle appliance. Because of the required conditional "and" requirement, I would make two rules for this Web server. One for the destination IP address over port 80, and one for the same IP address for port 443. Figure B shows the QoS rule created for port 80 for the Web server. Figure B
The QoS module is kept in the Web management interface rather than in the virtual rack java applet that features the Web filter, OpenVPN server, and other components. I have been using the Untangle gateway at home now for a few months and have been very happy with the appliance. I see this device as a great solution for small offices and an open source springboard for advanced applications. More information can be found on the Untangle Web site.
