Is a tunneling protocol used to connect from one VPN server to another. However, there are better (more secure and reliable) alternatives. Wireguard

What is DNS Tunneling? | DDI (Secure DNS, DHCP, IPAM DNS Tunneling is a method of cyber attack that encodes the data of other programs or protocols in DNS queries and responses. DNS tunneling often includes data payloads that can be added to an attacked DNS server and used to control a remote server and applications. What Is PPTP? (Everything You Need to Know) | CactusVPN Jan 22, 2019 Tunneling protocol dictionary definition | tunneling tunneling protocol definition: A network protocol that encapsulates packets at a peer level or below. It is used to transport multiple protocols over a common network as well as provide the vehicle for encrypted virtual private networks (VPNs). It is said to Layer 2 Tunneling Protocol L2TP/IPsec | ExpressVPN

Tunneling, also known as “port forwarding,” is the method of transmitting private network data and protocol information through public network by encapsulating the data. Tunneling is when instead of sending a packet directly through the network, the data is sent inside another encrypted connection.

The Point-to-Point Tunneling Protocol (PPTP) is an obsolete method for implementing virtual private networks.PPTP has many well known security issues. PPTP uses a TCP control channel and a Generic Routing Encapsulation tunnel to encapsulate PPP packets. Many modern VPNs use various forms of UDP for this same functionality.. The PPTP specification does not describe encryption or authentication What is GRE tunneling? | How GRE protocol works | Cloudflare Encapsulating packets within other packets is called "tunneling." GRE tunnels are usually configured between two routers, with each router acting like one end of the tunnel. The routers are set up to send and receive GRE packets directly to each other. What's the difference between tunneling and VPN? - Quora

What is Point-to-Point Tunneling Protocol (PPTP

Tunneling is also known as port forwarding. Tunneling is a protocol that allows the secure movement of data from one network to another. Tunneling involves enabling private network communications to be sent across a public network, such as the Internet, through a process called encapsulation.
