• Point-to-Point Tunneling Protocol — Provides a secure tunnel

for remote client access to a PPTP security gateway. PPTP

includes provisions for call origination and flow control required

by ISPs.

• L2TP merges the best features of PPTP and L2F — Like PPTP,

L2TP requires that the ISP’s routers support the protocol.

• IP Security — Provides IP network-layer encryption. IPSec can

support large encryption networks (such as the Internet) by using

digital certificates for device authentication.
