Instant Broadband™ Series

If DMZ Hosting is used, does the exposed user share the public IP with the Router? No.

Does the Router pass PPTP packets or actively route PPTP sessions? The router

allows PPTP packets to pass through.

Is the Router cross-platform compatible? Any platform that supports Ethernet and TCP/IP is compatible with the router.

How many ports can be simultaneously forwarded? Theoretically, the router can establish 520 sessions at the same time, but you can only forward 10 ranges of ports.

Does the Router replace a modem? Is there a cable or DSL modem in the Router? No, this version of the router must work in conjunction with a cable or DSL modem.

Which modems are compatible with the Router? The router is compatible with virtually any cable or DSL modem that supports Ethernet.

What are the advanced features of the Router? The Router's advanced features include IP Filtering, IP Forwarding, Dynamic Routing, Static Routing, DMZ hosting, and MAC Address Cloning.

What is the maximum number of VPN sessions allowed by the Router?

One VPN session at a time.

How big is the memory buffer on the Router? 512KB.

How can I check whether I have static or DHCP IP Addresses? Consult your ISP

to obtain this information.

How do I get mIRC to work with the Router? Under the Forwarding tab, set port forwarding to 113 for the PC on which you are using mIRC.

Glossary

10BaseT - An Ethernet standard that uses twisted wire pairs.

100BaseTX - IEEE physical layer specification for 100 Mbps over two pairs of Category 5 UTP or STP wire.

1000BASE-T - Provides half-duplex (CSMA/CD) and full-duplex 1000 Mbps Ethernet service over Category 5 links as defined by ANSI/TIA/EIA-568-A. Topology rules for 1000BASE-T are the same as those used for 100BASE-T. Category 5 link lengths are limited to 100 meters by the ANSI/TIA/EIA-568- A cabling standard. Only one CSMA/CD repeater will be allowed in a collision domain.

Adapter - Printed circuit board that plugs into a PC to add to capabilities or connectivity to a PC. In a networked environment, a network interface card (NIC) is the typical adapter that allows the PC or server to connect to the intranet and/or Internet.

Auto-negotiate- To automatically determine the correct settings. The term is often used with communications and networking. For example, Ethernet 10/100 cards, hubs, and switches can determine the highest speed of the node they are connected to and adjust their transmission rate accordingly.

Backbone – The part of a network that connects most of the systems and net- works together and handles the most data.

Bandwidth - The transmission capacity of a given facility, in terms of how much data the facility can transmit in a fixed amount of time; expressed in bits per second (bps).

Bit – A binary digit. The value—0 or 1—used in the binary numbering system. Also, the smallest form of data.

Boot – To cause the computer to start executing instructions. Personal comput- ers contain built-in instructions in a ROM chip that are automatically executed on startup. These instructions search for the operating system, load it, and pass control to it.

Bottleneck – A traffic slowdown that results when too many network nodes try to access a single node, often a server node, at once.

Bridge - A device that interconnects different networks together.
