Remote Access Policy

Remote access is a broad concept. In general, it defines how the user can connect to the LAN, or from the LAN to outside resources (that is, the Internet). Connectivity is possible in many ways: dial-in, ISDN, wireless bridges, and secure Internet connections. Each method incurs its own advantages and disadvantages, and provides a unique challenge to providing AAA services. In addition to the method of
