P-793H v 2 Support Notes

Because users typically dial the their local ISP for VPN, thus, long distance
phone charge is reduced than making a long direct connection to the remote
office.
(2).Reducing number of access lines
Many companies pay monthly charges for two types access lines: (1) high-
speed links for their Internet access and (2) frame relay, ISDN Primary Rate
Interface or T1 lines to carry data. A VPN may allow a company to carry the
data traffic over its Internet access lines, thus reducing the need for some
installed lines.

3. What are most common VPN protocols?

There are currently three major tunneling protocols for VPNs. They are Point-
to-Point Tunneling Protocol (PPTP), Layer 2 Tunneling Protocol (L2TP) and
Internet Protocol Security (IPSec).

4. What is PPTP?

PPTP is a tunneling protocol defined by the PPTP forum that allows PPP
packets to be encapsulated within Internet Protocol (IP) packets and
forwarded over any IP network, including the Internet itself. The PPTP is
supported in Windows NT and Windows 98 already. For Windows 95, it
needs to be upgraded by the Dial-Up Networking 1.2 upgrade.

5. What is L2TP?

Layer Two Tunneling Protocol (L2TP) is an extension of the Point-to-Point
Tunneling Protocol (PPTP) used by an Internet service provider (ISP) to
enable the operation of a virtual private network (VPN) over the Internet.

6. What is IPSec?

IPSec is a set of IP extensions developed by IETF (Internet Engineering Task
Force) to provide security services compatible with the existing IP standard
(IPv4) and also the upcoming one (IPv6). In addition, IPSec can protect any
protocol that runs on top of IP, for instance TCP, UDP, and ICMP. The IPSec
provides cryptographic security services. These services allow for
authentication, integrity, access control, and confidentiality. IPSec allows for the
information exchanged between remote sites to be encrypted and verified. You
can create encrypted tunnels (VPNs), or just do encryption between computers.
Since you have so many options, IPSec is truly the most extensible and
complete network security solution.

7. What secure protocols does IPSec support?
