password. In CHAP, additionally to user name and password the Zyxel Device sends regular
challenges to make sure an intruder has not replaced a peer. CHAP is more secure than PAP;
however, PAP is available on more platforms. Select an authentication protocol (Auto, CHAP or
PAP). Contact your service provider for the correct authentication type.
