Point-to-point Tunneling protocol and Layer 2 Tunneling Protocols

The Point-to-Point Tunneling Protocol is a set of communication rules which allow
different corporations to increase their corporate network by use of private tunnels over the
public market. This type of protocol usually captures the Point-to-Point frames to IP datagrams
for the transmission over an internet which is IP-based like a private intranet or internet. The
PPTP makes use of TCP connection which known as PPTP control connection in creating,
maintaining, and terminating tunnel and also a modified version of Generic Routing
Encapsulation which captures the PPP frames like a tunneled data. The PPTP offers a faster as
well as easy way of setting up solution for the users who are not much concerned with security.
It is also the simplest and quickest method of the VPN to set up with Tomato firmware or DDWRT. In addition, it is compatible with wide range of platforms. Nevertheless, it is not
recommended by many tech experts mainly because it has well-reported security flaws.

Layer Two Tunneling Protocol is a protocol used to support the VPNs and it acts like an
extension of Point-to-Point Tunneling Protocol. This type of protocol does not offer any
confidentiality or encryption by itself but it depends on the encryption protocol which it passes
within a tunnel so as to offer ...

Really great stuff, couldn't ask for more.
