VTun is the easiest way to create Virtual Tunnels over TCP/ IP networks with traffic shaping, compression, and encryption. It supports IP, Ethernet, PPP and other tunnel types. VTun is easily and highly configurable. VPN, Mobile IP, Shaping, etc
Nov 14, 2019 · Virtual private network technology is based on the concept of tunneling.Just like a water pipe contains the liquid flowing inside of it, a VPN tunnel insulates and encapsulates internet traffic—usually with some type of encryption—to create a private tunnel of data as it flows inside an unsecured network. Types of Tunnels: IPIP GRE EOIP L2TP PPTP layer3 tunnel layer 3 tunnel layer 2 tunnel layer 2 tunnel layer2 tunnel www.netrotik.com 4 for ipv4 and 41 for ipv6 IP protocol number 47 IP protocol number 47 1701 UDP 1723 TCP As of version 0.60, Ping Tunnel supports authentication. The authentication used is very simple, and works as follows. The user first specifies a password or passphrase, which is then hashed using the MD5 algorithm (Ping Tunnel uses the implementation by L. Peter Deutsch, available here. Note that the implementation is included with Ping Tunnel, so there is no need to download it separately). May 17, 2019 · IPIP tunnel, just as the name suggests, is an IP over IP tunnel, defined in RFC 2003. The IPIP tunnel header looks like: It’s typically used to connect two internal IPv4 subnets through public IPv4 internet. It has the lowest overhead but can only transmit IPv4 unicast traffic. That means you cannot send multicast via IPIP tunnel.

What is an IP tunnel? - Quora An IP tunnel consists of packets carried as payload inside (other) IP packets. An analogy is putting a piece of mail inside another envelope, which is mailed in turn. This tunneling function is implemented by certain routers or gateways that keep

IP-IP Tunnel :: Chapter 11. VPN Technologies, Tunnel The Linux ip tunnel command sequence (Example 11-1) offers several other options such as tunnel keys, TTL/TOS manipulation, and other features. I do not recommend using keys or TOS options for tunnel setup with non-Linux/Cisco gateways for compatibility reasons.
