What is L2TP?

An acronym for Layer 2 Tunneling Protocol, L2TP came into existence by associating the features of PPTP and Layer 2 Forwarding (L2F).

Same as PPTP, L2TP also depends on Point-to-Point Protocol (PPP) for encryption and does not provide it on its own.

PPP comes handy in performing user authentication and besides this, it also assures computer authentication that further makes way for an added security level.

Furthermore, in order to provide strong authentication and confidentiality L2TP packers are often secured by using IPSec protocol and it is due to this reason that the combination of both these protocols is termed as L2TP/IPSec.

The destination server over a public network. As compared to PPTP VPN which assures data confidentiality, L2TP holds a slight edge since it promises much more advantageous features, such as:

  • Data integrity: That prevents browsing data from modification and interception with the during its transmission from one point to another via L2TP
  • Data Authentication: Confirms that the data has really been sent by a genuine person and not by any intruder to spread malware in your network.
  • Replay Protection: Hampers the attempts of hackers to track the user data such as login credentials.
  • Diversified Usability: Can be leveraged on various non-IP networks as well that may include X.25, ATM and frame relay among others.
  • Data confidentiality: L2TP shares this feature along with PPTP. As the name suggests, the protocol keeps the data totally secure and confidential, only to be used by the intended owner and not any third party.
