| protocolo de túnel de capa dos | Layer Two Tunneling Protocol An industry-standard Internet tunneling protocol that provides encapsulation for sending Point-to-Point Protocol (PPP) frames across packet-oriented media. For IP networks, L2TP traffic is sent as User Datagram Protocol (UDP) messages. In Microsoft operating systems, L2TP is used in conjunction with Internet Protocol security (IPSec) as a virtual private network (VPN) technology to provide remote access or router-to-router VPN connections. L2TP is described in RFC 2661 (L2TP) |
| Protocolo de túnel punto a punto | Point-to-Point Tunneling Protocol (Networking technology that supports multiprotocol virtual private networks (VPNs), enabling remote users to access corporate networks securely across the Internet or other networks by dialing into an Internet service provider (ISP) or by connecting directly to the Internet. PPTP tunnels, or encapsulates, Internet Protocol (IP) or Internetwork Packet Exchange (IPX) traffic inside IP packets. This means that users can remotely run applications that depend on particular network protocols. PPTP is described in RFC 2637) |
| servidor de túnel | tunnel server (A server or router that terminates tunnels and forwards traffic to the hosts on the target network) |
| túnel IP en IP | IP-in-IP tunnel (The encapsulation of an IP multicast datagram within an IP unicast datagram, so as to forward information between endpoints in an IP internetwork that have differing capabilities, thus acting as a logical link between the endpoints) |
| túnel voluntario | voluntary tunnel (A tunnel that is initiated by the client. A voluntary tunnel tunnels Point-to-Point Protocol (PPP) over Internet Protocol (IP) from the client to the tunnel server, and then the data is forwarded to the target host by the tunnel server) |
