I'm working with an organization that would like to start using a old Barracuda Spam Filter 300 unit. I've sold and configured plenty of these, but was surprised to see that this unit's warranty lapsed by 6 months. The company was acquired and this equipment came along in the transfer. I called in to Barracuda and was promptly directed to their Warranty and License agreement. In short, they will not renew or extend a warranty on their hardware products to anyone except for the original owner. No exceptions! This means no firmware or virus updates.
A little more probing and I discovered dozens of used Barracuda devices on eBay available for a tiny fraction of the original price because they are ineligible for Barracuda's subscription firmware and updates. This is upsetting, as these units are basically "bricked" from the manufacturer's perspective. The rigid practice of not allowing ownership transfers is ridiculous.
I did find a company, BarracudaPro, that focuses on restoration and repair of these units, but I'm curious if any other admins are running their Barracuda Spam/Web Filters without updates in an unsupported capacity. Any problems? Anything to watch out for?
