What is VPN Tunneling Packets?- VPN Tunneling Packets are packets to transmit over VPN in a specific VPN protocol format.
- These packets are encapsulated within some other base or carrier protocol followed by transmission between VPN client and VPN server.
- Finally, at the receiving side, de-encapsulation takes place.
- Tunneling enables the encapsulation of a packet from one type of protocol within the datagram of a different protocol.
- For example, PPTP is used by VPN to encapsulate IP packets over a public network, such as the Internet.
- A VPN solution based on Point-to-Point Tunneling Protocol (PPTP), Layer Two Tunneling Protocol (L2TP), or Secure Socket Tunneling Protocol (SSTP) can be configured.
- PPTP, L2TP, and SSTP depend heavily on the features originally specified for Point-to-Point Protocol (PPP).
- PPP was designed to send data across dial-up or dedicated point-to-point connections.
- For IP, PPP encapsulates IP packets within PPP frames and then transmits the encapsulated PPP-packets across a point-to-point link.
- PPP was originally defined as the protocol to use between a dial-up client and a network access server.
