PPTP
Point-to-Point Tunneling Protocol (PPTP) is a protocol developed by Microsoft targeted at
creating VPN connections over the Internet. This enables remote users to access the
gateway via any ISP that supports PPTP on its servers. PPTP encapsulates network traffic,
encrypts content using Microsoft's Point-to-Point Encryption (MPPE) protocol that is based
on RC4, and routes using the generic routing encapsulation (GRE) protocol.
With your gateway, PPTP is targeted at serving two purposes:
1.
Connecting the gateway to the Internet when it is used as a cable modem, or when
using an external cable modem. Such a connection is established using user name
and password authentication.
2.
Connecting the gateway to a remote network using a Virtual Private Network (VPN)
tunnel over the Internet. This enables secure transfer of data to another location over
the Internet, using user name and password authentication.
