L2TP+IPsec
Layer 2 Tunneling Protocol (L2TP) is an standard protocol for encapsulating PPP
data packets and passing them transparently across an IP network. Typically,
L2TP is used as a tunneling protocol to support VPNs. It does not provide
security (encryption or confidentiality) by itself, but relies on an encryption
protocol that it passes within the tunnel for security.
L2TP is a point-to-point connection tunnel establishment. L2TP by default uses
UDP port 1701.
PPP sessions within the L2TP tunnel supports the following authentication using
username and password:
• PA P
• CHAP
• MSCHAPv1
• MSCHAPv2
The authentication method used in the connection is selected through negotiation
between the PPP endpoints. The PPP configuration is only available on VPN
tunnel.
