17 Remote users connections
17.1 Principles
A remote user connection is a tunnel set between a remote PC and a router providing the RAS
function (Remote Access Service), like the RAS-3G.
A remote user connection provides security and simplicity advantages :
• The remote user is identified with a login in and password or eventually a certificate.
• The data is encrypted (TLS or L2TP).
• An IP address belonging to the local network is automatically assigned to the remote user’s PC.
The RAS-3G manages PPTP and TLS or L2TP remote connections.
Only one type can be selected. It will apply to all the remote users connections.
A PPTP is the simplest type of remote user connection; data is not encrypted.
The remote user can be identified only with a login and password.
A TLS connection provides encryption; moreover; the remote user can be identified with a log in and
password and with a certificate if necessary.
