The Remote Access role allows you to do a few different things. It can provide connectivity to your network with DirectAccess and VPNs, and also offers a web application proxy. At its core, Remote Access is designed to be a VPN solution. Routing and Remote Access Service provides a traditional VPN service to support connectivity to your internal network, while DirectAccess offers end users a more seamless experience with VPN-like functionality. Your users will not have to stop or start their VPN connections; with DirectAccess, they’re connected to your organization when they have a good Internet connection. If you install the web application proxy, you can publish HTTP- and HTTPS-based web applications to devices on and off your network. The Routing functionality provides very similar functionality to a traditional router, including network address translation (NAT) and other methods needed to perform routing on an IP network.
