Wireless-G Travel Router with SpeedBooster

The Applications and Gaming Tab - Port Range Forwarding

The

Port Range Forwarding

screen allows you to set up public services on your network, such as web servers, ftp

servers, e-mail servers, or other specialized Internet applications. (Specialized Internet applications are any

applications that use Internet access to perform functions such as videoconferencing or online gaming. Some

Internet applications may not require any forwarding.)

Before using forwarding, you should assign static IP addresses to the designated PCs.

Port Range Forwarding

To forward a port, enter the information on each line for the criteria required. Descriptions of each criteria are

described here.

Application Name

. Each drop-down menu offers a choice of ten preset applications (select

None

if you do not

want to use any of the preset applications). Select up to five preset applications. For custom applications, enter

the name of your application in one of the available fields.

The preset applications are among the most widely used Internet applications. They include the following:

DNS

(Domain Name System). The way that Internet domain names are located and translated into IP addresses. A

domain name is a meaningful and easy-to-remember “handle” for an Internet address.

Finger

. A UNIX command widely used on the Internet to find out information about a particular user, such as a

telephone number, whether the user is currently logged on, and the last time the user was logged on. The person

being “fingered” must have placed his or her profile on the system in order for the information to be available.

Fingering requires entering the full user@domain address.

FTP

(File Transfer Protocol). A protocol used to transfer files over a TCP/IP network (Internet, UNIX, etc.). For

example, after developing the HTML pages for a website on a local machine, they are typically uploaded to the

web server using FTP.

POP3

(Post Office Protocol 3). A standard mail server commonly used on the Internet. It provides a message store

that holds incoming e-mail until users log on and download it. POP3 is a simple system with little selectivity. All

pending messages and attachments are downloaded at the same time. POP3 uses the SMTP messaging protocol.

SMTP

(Simple Mail Transfer Protocol). The standard e-mail protocol on the Internet. It is a TCP/IP protocol that

defines the message format and the message transfer agent (MTA), which stores and forwards the mail.

tcp

: a network protocol for transmitting data

that requires acknowledgement from the

recipient of data sent.

udp

: a network protocol for transmitting data

that does not require acknowledgement from

the recipient of the data that is sent.

SNMP

(Simple Network Management Protocol). A widely used network monitoring and control protocol. Data is

passed from SNMP agents, which are hardware and/or software processes reporting activity in each network

device (hub, router, bridge, etc.) to the workstation console used to oversee the network. The agents return

information contained in a MIB (Management Information Base), which is a data structure that defines what is

obtainable from the device and what can be controlled (turned off, on, etc.).

Telnet

. A terminal emulation protocol commonly used on Internet and TCP/IP-based networks. It allows a user at

a terminal or computer to log onto a remote device and run a program.

TFTP

(Trivial File Transfer Protocol). A version of the TCP/IP FTP protocol that has no directory or password

capability.

Web.

The Internet.

Start/End Port

. This is the port range. Enter the port number or range of external ports used by the server or

Internet application. Check with the software documentation of the Internet application for more information.

Protocol

. Select the protocol(s) used for this application,

TCP

and/or

UDP

.

To IP Address

. For each application, enter the IP address of the PC running the specific application.

Enabled

. Click the

Enabled

checkbox to enable port forwarding for the relevant application.

Wireless-G Travel Router with SpeedBooster

The Applications & Gaming Tab - Port Range Triggering

The

Port Range Triggering

screen allows the Router to watch outgoing data for specific port numbers. The IP

address of the computer that sends the matching data is remembered by the Router, so that when the requested

data returns through the Router, the data is pulled back to the proper computer by way of IP address and port

mapping rules.

Port Range Triggering

Application Name

. Enter the application name of the trigger.

Triggered Range

. For each application, list the triggered port number range. Check with the Internet application

documentation for the port number(s) needed. In the first field, enter the starting port number of the Triggered

Range. In the second field, enter the ending port number of the Triggered Range.

Forwarded Range

. For each application, list the forwarded port number range. Check with the Internet

application documentation for the port number(s) needed. In the first field, enter the starting port number of the

Forwarded Range. In the second field, enter the ending port number of the Forwarded Range.

Enabled

. Click the

Enabled

checkbox to enable port range triggering for the relevant application.

The Applications and Gaming Tab - DMZ

Wireless-G Travel Router with SpeedBooster

The Applications and Gaming Tab - DMZ

The DMZ feature allows one network user to be exposed to the Internet for use of a special-purpose service such

as Internet gaming or videoconferencing. DMZ hosting forwards all the ports at the same time to one PC. The Port

Range Forwarding feature is more secure because it only opens the ports you want to have opened, while DMZ

hosting opens all the ports of one computer, exposing the computer to the Internet.

Any PC whose port is being forwarded must have its DHCP client function disabled and should have a new static

IP address assigned to it because its IP address may change when using the DHCP function.

DMZ

To expose one PC, select

Enabled

, then enter a WAN IP Address or Host IP Address in the field.

Wan IP Address

. The Internet IP address of the computer you want to expose.

Host IP Address

. Enter the IP address of the computer you want to expose.
