WAN connection The Cayman series Gateway supports PPPoE eliminating the need to install PPPoE client software on any LAN computers Service Providers may require the use of PPP authentication protocols such as Challenge Handshake Authentication Protocol CHAP or Password 16 Overview of Major Capabilities Authentication Protocol PAP CHAP and PAP use a username and password pair to authenticate users with a PPP server A CHAP authentication process works as follows 1 The password is used to scramble a challenge string 2 The password is a shared secret known by both peers 3 The unit sends the scrambled challenge back to the peer PAP a less robust method of authentication sends a username and pass word to a PPP server to be authenticated PAP s username and password pair are not encrypted and are therefore sent unscrambled Instant On PPP You can configure your Gateway for one of two types of Internet connections Always On nstant On These selections provide either an uninterrupted Internet connection or an as needed connection While an Always On connection is convenient it does leave your network permanently connected to the Internet and therefore potentially vulnerable to attacks Cayman s Instant On technology furnishes almost all the benefits of an Always On connection while providing two additional security benefits Your network cannot be attacked when it is not connected Your netw
