What Can the OCR 812 Do?
The OCR 812 is a stand-alone BRouter with data interfaces
to a Local Area Network (LAN) and a Wide Area Network
(WAN).
A BRouter is a router with bridging capability that
understands how to route specific types of packets, such as
TCP/IP packets. The bridge function of the Brouter forwards
packets to other network(s) connected to the device.
The following is a representation of how your OCR 812
connects a LAN and WAN:

Ta bl e 1- 1 OCR 812 Features
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.
1-4 CHAPTER 1: GETTING STARTED
Generic Routing Encapsulation (GRE) A proposed Internet protocol
transported within other tunneling
protocols in a VPN.
ADSL WAN interface port Contains one port that connects to the
wide area network (WAN).
Asynchronous Transfer Mode (ATM) A network technology that transmits
video, audio, and computer data packets
in very small sizes over the same
network.
RFC 1483 protocol A defined protocol standard that
describes two encapsulation methods,
routed and bridged, for carrying
network traffic over ATM.
LAN interface A four-port Ethernet 10Base-T hub.
Networked workstations Allow one or more to connect to other
computers on a remote LAN and also
provide high-speed access to the
Internet.
Bridging Supports learning bridge and 802.1d
spanning tree functionality to eliminate
loops.
Internet Protocol (IP) and Internetwork
Packet Exchange (IPX) protocols
A protocol used to route data from
source to destination.
Routing Information Protocol (RIP) Specifies how routers exchange routing
table information.
Simple Network Management Protocol
(SNMP)
Provides a set of protocols for managing
complex networks.
Address translation Using Dynamic NAT, Static NAT,
SuperNAT, and Intelligent PAT.
Dynamic Host Configuration Protocol
(DHCP)
A protocol for assigning dynamic IP
addresses to devices on a network.
DHCP also provides services for your
LAN, including automatic assignment of
IP addresses to workstations.
Telnet Connects your PC to a server on the
network.
Packet filtering Provides an extensive set of data filtering
capabilities.
OCR 812 Manager Contains the Web-based online users
guide, Tools, Configuration, and
Monitor modes that support your 812
configuration. These modes have online
Help for each configuration function.
Ta bl e 1- 1 OCR 812 Features
What Are the Features of This Product? 1-5
The following are new features for the current release:
SuperNAT
SuperNAT is an address translation protocol that is
activated when data packets arrive destined for a public
address that matches both NAT and PAT rules. SuperNAT
first tries to use NAT address translations. If this does not
work, PAT address translation is used. You can configure
SuperNAT from the Web pages or the CLI.
NOTE: You cannot use the public WAN port IP address of
the OfficeConnect 812 as one of the NAT or SuperNAT
static or dynamic public IP addresses.
Virtual Private Networks
A Virtual Private Network (VPN) is a computer network that
contains characteristics of a private network operating
through the public infrastructure, like the Internet. You can
use several tunneling and encryption protocols to configure
a VPN and ensure that data remains secure in a private
tunnel that simulates a point-to-point connection.
Tunneling Protocols
Tunneling allows workstations on one network to send
data by encapsulating it in an IP data stream. You use
tunneling to move data between administrative domains
that use a protocol not supported by the Internet that
connects those domains.
The following are tunneling protocols:
L2TP - Layer Two Tunneling Protocol, an extension to
the PPP protocol that enables Internet Service Providers
(ISPs) to operate VPNs. L2TP merges the best features of
two other tunneling protocols: PPTP from Microsoft and
L2F from Cisco Systems. Like PPTP, L2TP requires that
the ISP's routers support the protocol.
PPTP - Point-to-Point Tunneling protocol, ensures the
security of messages transmitted from one VPN to
another. Generic Routing Encapsulation (GRE), a
proposed protocol that encapsulates and transports the
data portion of packets as they are routed, is also
1-6 CHAPTER 1: GETTING STARTED
supported. No additional configuration of the OCR 812
is required to support GRE.
Encryption Protocols
Microsoft Point-to-Point Encryption (MPPE) encrypts data in
PPTP VPN connections. MPPE provides privacy to a tunnel.
When you use MPPE and PPTP together, a VPN is created.
You can set the MPPE protocol on the Tunnel Modify web
page using the Encryption Algorithm field. From the CLI,
you set MPPE by specifying MSCHAPv1. See the CLI User
Guide for more information.
SIP Phone Support
Session Initiation Protocol (SIP) is an IP protocol that
supports a networked telephone that converges voice and
data on a single network. This instrument is a smart device
that performs many of the functions that are traditionally
handled by the phone companys central office equipment.
When you connect SIP and the OCR 812, the SIP phone is
registered with the proxy server supplied by your ISP. If you
want to use SIP and NAT, you must select the PAT option of
NAT. For more information, see the Remote 812 ADSL
Router Online Users Guide.
OCR 812 Boot Mode Options
To simplify the installation process, the OCR 812 can be
initialized with pre-configured parameters using the DIP
switches located on the back of the unit. These are the
Boot Mode options:
DHCP Smart Mode
Bridge Mode
