RAS Server
VPN Server
RAS server primarily enables remote access to a network by allowing users to dial in using a modem or ISDN connection.
A VPN server creates a secure connection over a public network, such as the Internet, allowing remote users to access a private network securely.
RAS server provides dial-up connectivity and supports protocols like PPP (Point-to-Point Protocol) and SLIP (Serial Line Internet Protocol).
VPN server establishes a secure tunnel by encrypting the data transmitted between the remote user and the private network using protocols like IPSec (Internet Protocol Security) or SSL/TLS (Secure Sockets Layer/Transport Layer Security).
RAS server is typically used for remote access to internal network resources, such as file shares or printers.
VPN server allows remote users to access the entire network as if they were physically present on the organization's premises.
RAS servers may require additional hardware, such as a modem bank or ISDN adapter, to support dial-up connections.
VPN servers can be implemented using software-based solutions or dedicated VPN appliances without requiring additional hardware in most cases.
