Translations:IPsec L2TP VPN server/122/en

The easiest way to setup pppd is to not use any authentication at all. In that case, make sure "noauth" is specified. This is useful for testing purposes, but otherwise not recommended - especially when using PSK. For certain PKI setups, such a configuration may be sensible - for example,
 * all the client machines are fully trusted and under control, or
 * all the users are trusted and the keys are on machines no one else, besides the users' themselves, have access to, or
 * all connections are unattended (using this method to connected multiple sites)
