OCR 812 Features Feature Description
Super Network Address Translation
(SuperNAT) Uses Network Address Translation (NAT)
and Port Address Translation (PAT)
intelligently together to send packets
over the network, and translates public
addresses to private ones.
Port Address Translation (PAT) An address translation protocol that
supports simultaneous connections from
different workstations on the LAN with
one public IP address.
Network Address Translation (NAT) An address translation protocol that
supports simultaneous connections from
different workstations on the LAN with
one or more public IP addresses. The
mapping can be done dynamically or
statically.
There are two types of NAT:
Dynamic NAT — Dynamically maps a
public address from a
pool of
addresses to the private address of
your workstation on your LAN.
Static NAT— Statically maps a public
address to the private address of your
workstation on your LAN.
Virtual Private Network (VPN) A protected computer network that acts
like a private network over the Internet.
When the MPPE and PPTP protocols are
used together, a VPN is created.
Point-to-Point Protocol (PPP) Negotiates and establishes a connection
between two peers to provide a
standard method for transporting
multi-protocol datagrams over
point-to-point links. Sets the MSCHAPv1
authentication protocol.
Layer Two Tunneling Protocol (L2TP),
Point-to-Point Tunneling Protocol (PPTP) Tunneling protocols that you use to
protect and configure a VPN.
MPPE An encryption protocol used to make a
tunnel private.
Supported by Microsoft CHAPv1, an
authentication protocol set with the
PPP command.
Session Initiation Protocol (SIP) Support Allows SIP telephones to connect to
Ethernet ports.
