RRAS (Routing and Remote Access Service) is a Microsoft Windows server role that enables routing and remote access functionality in a computer network. It provides a set of network services that allow users to connect to a local area network (LAN) or wide area network (WAN) and access resources remotely. RRAS can be configured to perform various tasks, including routing IP packets between different networks, providing virtual private network (VPN) connections, and offering dial-up and remote access services.
In terms of routing, RRAS acts as a router by transmitting network traffic between two or more networks. It can forward packets based on the destination IP address or other criteria defined by routing protocols. This feature allows multiple networks to communicate with each other, optimizing network performance and connectivity.
Additionally, RRAS supports VPN connections, allowing users to access a private network securely over a public network such as the internet. It uses encryption and authentication mechanisms to establish a virtual tunnel between the client and server, ensuring data confidentiality and integrity.
Furthermore, RRAS provides dial-up and remote access services, enabling users to connect to a network remotely via telephone lines or other means. This allows users to access network resources and services as if they were physically connected to the LAN or WAN.
Overall, RRAS is a versatile Windows server role that enables routing and remote access functionality, facilitating network communication, secure remote connections, and access to network resources.
