Tunnel Protocols

H Point-to-Point Tunneling Protocol (PPTP) developed by Microsoft,
3Com and others that uses Point-to-Point (PPP) protocol and Generic
Routing Encapsulation (GRE) to route packets through the Internet.
H IP Security (IPSec) protocol developed by the Internet Engineering
Task Force (IETF) that adds security extensions for encryption and
message authentication to IP protocol.
For each tunnel protocol, you can configure authentication, encryption, and
compression parameters. To set tunnel protocol parameters, perform the
