This means you can theoretically use any router regardless of the medium such as a DSL, VSAT, T1, T3, ISDN, and 3G. Anything that can connect to the Internet and provide a DHCP address to the RED device plugged into it will do. You also need an Internet break out at your remote site. They are purchased as a once off cost with no annual subscription required. The good thing is that they are relatively inexpensive. Unfortunately there are no virtual RED devices, so you have to get the hardware. It also means all users, regardless of site can be reported on with the same infrastructure. This allows you to have a consistent user security profile across all of your sites. Once your RED is configured all of your devices on the remote site can be set to browse the Internet through your central UTM. The concept is not new, but the ease of implementing it, and the elimination of remote side configuration is what makes it really cool. The RED or Remote Ethernet Device is a small box you deploy to your remote sites, and it establishes a VPN back to your central Sophos UTM so that anything connected to the RED is seen as part of your network. One of the very first features of Sophos UTM that grabbed me as a seriously cool feature is the Sophos RED device integration.
