Sounds like what I'm really after, so I had a quick look on ebay and found this...
Sophos UTM 120 Hardware Appliance rev. 5 OS Version 9.508-10.1 year 2013
Home licence ready
Network, Web-, Email-,Wireless- und Webserver-Protection, RED, Site-2-Site- and Remote Access-VPN
Sounds good to me... But I really don't have a clue
What do you reckon?
