Remote 812 Local Connection If you want to attach locally to the OfficeConnect Remote 812 via the console (serial) port, you will need to connect the supplied serial cable to the Console Port located on the unit and the Serial Port on your computer. In addition, you will also need a terminal emulation program appropriate for your computer.
Page 18: Unix-Based Computers
Remote Connection If you want to attach to the OfficeConnect Remote 812 via the LAN or WAN interface of the unit, you will need to establish a Telnet connection to the unit. The OfficeConnect Remote 812 must have an IP address and an administrative login profile (username and password) in order to connect to it with Telnet.
Page 19: Cli Command Conventions And Terminology
CLI C This chapter describes the command syntax, conventions and terminology used within the Command Line Interface. Reviewing and understanding this chapter is essential for you to understand subsequent chapters. Command Structure Format Commands can be followed by values and/or parameters and values. For example: add ip network <network_name>...

The current command can be killed by pressing <ctrl>c [^ c]. A partially completed command line can be reprinted - a useful function if, due to interrupted output, you’re unsure what OfficeConnect Remote 812 has “seen” up to now - by pressing <ctrl>l [^ l] (for last).
Page 21: Conventions
Conventions Conventions Most commands are not case sensitive. As a rule, only <name> and [password] values require typing the correct case. Configuration changes occur immediately but are lost on reboot unless you save them. The save all command places configuration changes in FLASH ROM (permanent memory).

If you choose to run NAT the WAN interface must be Numbered. (i.e., there must be a local WAN-side IP address specified that must be on a different IP network than the LAN-side IP address). See Appendix B of the OfficeConnect Remote 812 ADSL Router User’s Guide for a discussion of Numbered and Unnumbered interfaces.
Page 36: Ipx Routing (Network Service Ppp)
Question Do you want to Bridge any traffic over VC “name”? The OfficeConnect Remote 812 can be configured to send and receive the routed (IP and IPX) packets using bridged encapsulation (i.e., Bridged-1483 or BRCP or PP), where the MAC-header is included in each packet. The routing rules for [IP and IPX] will be applied to each packet.

OfficeConnect Remote 812 and the remote site. The OfficeConnect Remote 812 supports two types of Network Services: PPP and RFC 1483. The OfficeConnect Remote 812 and the remote site must both use the same Network Service in order for a connection to established and maintained.
Page 42: Ip Routing
ATM Category of Service parameters specify characteristics (sometimes called traffic shaping parameters) for data transmitted from the OfficeConnect Remote 812 to the remote site. They have no effect on data transmitted from the remote site to the OfficeConnect Remote 812.

255.255.255.255 for the <ip address> parameter. To specify that the interface is Unnumbered you must enter 0.0.0.0 for the <ip address> parameter. (See Appendix B of the OfficeConnect Remote 812 ADSL Router User’s Guide for a discussion of Unnumbered interfaces.) Optionally, you can specify that the remote site should be used as the default gateway.
Page 46: Configuring Ip Rip For A Remote Site
Validation is enabled, the source address of all IP frames received from the remote site will be validated. A packet’s source address is valid if the OfficeConnect Remote 812 will route an IP frame destined to the source address on the same VC it came in on.
Page 47: Address Translation
Remember to disable and then re-enable the VC profile for the change to take effect. IP Tools The OfficeConnect Remote 812 CLI provides a standard set of IP utility programs including Ping, TELNET and RLOGIN. Address Public IP addresses are registered and can be used within a public network (e.g., Translation the Internet).
Page 48: Configuring Nat
For example, if you want to support a Web Server on the LAN and be able to manage your OfficeConnect Remote 812 with the Web Browser, you would define 2 static ports for the Web Server (TCP port 80).

Page 57: Bridging
Bridging A bridge connects two or more physical networks together to function as one big network. The OfficeConnect Remote 812 can be configured to be a learning bridge. A learning bridge does more than just link networks; it separates network traffic and forwards only the packets that need to be forwarded.
Page 58: Configuring Bridging For The Lan
<vc name> Bridging IP Traffic By default the OfficeConnect Remote 812 is set up to route IP traffic. To bridge IP traffic you must turn off IP Forwarding. IP Forwarding refers to the routing of IP packets from one interface to another. It does not affect communicating to the OfficeConnect Remote 812 itself.
Page 59: Mac-Encapsulated Routing
To the remote site, the packets appear as if they had been bridged. This feature allows the routing features of the OfficeConnect Remote 812 (i.e., address translation, DHCP Server, DNS Proxy, etc.) to be employed in a bridged environment.
