RAS is used in smaller networks where a dedicated dial-up router is not practical or possible. In a RAS setup, you can basically connect a modem to a Windows NT or Windows 2000 server and, by way of the RAS, configure that modem as dial-out only, dial-up only, or a combination.
How to use PPTP?
To use PPTP, you set up a PPP session between the client and server, typically over the Internet. Once the session is established, you create a second dial-up session that dials through the existing PPP session, using PPTP. The PPTP session tunnels through the existing PPP connection , creating a secure session.

What is VPN access?
A VPN allows a client to access a private network over a public network (such as the Internet). Remote access methods are useful for personnel that need access to the private network from remote locations.
What are the different authentication mechanisms?
The different authentication mechanisms that may be used with remote access services are: 1 PAP. Password Authentication Protocol. Passwords are sent in clear text so PAP is rarely used today. 2 CHAP. Challenge Handshake Authentication Protocol. CHAP uses a handshake process where the server challenges the client. The client then responds with appropriate authentication information. 3 MS-CHAP. Microsoft’s implementation of CHAP, which is used only by Microsoft clients. 4 MS-CHAPv2. An improvement over MS-CHAP. A significant improvement of MS-CHAPv2 over MS-CHAP is the ability to perform mutual authentication. 5 RADIUS. Remote Authentication Dial-In User Service. Radius provides a centralized method of authentication for multiple remote access services servers. RADIUS encrypts the password packets, but not the entire authentication process. 6 TACACS and XTACACS. Terminal Access Controller Access-Control System (TACACS) is a remote authentication protocol that was commonly used in UNIX networks. Extended TACACS (XTACACS) is an improvement over TACACS developed by Cisco Systems and is proprietary to Cisco systems. Neither of these are commonly used today with most organizations using either RADIUS or TACACS+. 7 TACACS+. Terminal Access Controller Access-Control System+ (TACACS) is an alternative to RADIUS and is proprietary to Cisco systems. A benefit of TACACS+ is that it can interact with Kerberos allowing it to work with a broader range of environments including Microsoft. Additionally, TACACS+ encrypts the entire authentication process (RADIUS encrypts only the password).
What port does Cisco VPN use?
TACACS+ has wider uses including as an authentication service for network devices. TACACS+ uses TCP port 49 .
What is L2TP tunneling?
Layer 2 Tunneling Protocol combines the strengths of Layer 2 Forwarding (L2F) and PPTP. L2TP is commonly used with IPsec for VPNs. Since NAT is not compatible with IPsec, L2TP/IPsec can’t go through a device running NAT. L2TP uses UDP port 1701. RADIUS.

What is VPN in Microsoft?
Point-to-Point Tunneling Protocol (PPTP), now commonly referred to as VPN (Virtual Private Networking) is Microsoft's version of PPP that encapsulates packets from other protocols for transmission over an IP network. It is used to create a secure network utilizing public lines (the Internet). VPN essentially enables users access to a secure corporate network from remote locations (such as from a salesperson's portable computer located in a hotel room). Prior to VPN, a dedicated rented line was required from point-to-point to assure high levels of security.

Why do you want to be encrypted in a remote session?
First, you want the best security you can provide for the remote session. You want authentication to be encrypted so that someone who is snooping cannot see it , and you want the data that is passed in the remote session to be encrypted for the same reason. Second, older systems and their associated protocols are less capable in terms ...
How does dial up authentication work?
Authenticating the user. Part of the dial-up process involves authentication, usually by providing a password. Since that password can be intercepted and used to gain unauthorized access, it should be encrypted using the strongest possible method that is supported by both the server and the client.
What is link encryption?
With link encryption, the data is encrypted only on the link (i.e., only to the remote access server); with end-to-end encryption, the data is encrypted from the client application to the server hosting the resource being accessed.
