Single Port Forwarding

PVC Connection Select

PVC stands for "Permanent Virtual Circuit".

It is a virtual circuit link between two nodes for ATM (Asynchronous

Transfer Mode) network. Each PVC functions as a separate Internet connection. You may set up to eight PVCs on

the Gateway.

PortMap List

The Single Port Forwarding screen provides options for customization of port services for common applications.

When users send this type of request to your network via the Internet, the Gateway will forward those requests to

the appropriate computer. Any computer whose port is being forwarded should 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.

Choose or enter the Application in the field. Then, enter the External and Internal Port numbers in the fields.

Select the type of protocol you wish to use for each application:

TCP

or

UDP

. Enter the IP Address in the field.

Click

Enabled

to enable Forwarding for the chosen application.

Port Range Forwarding

The Port Forwarding screen sets 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.)

When users send this type of request to your network via the Internet, the Gateway will forward those requests to

the appropriate computer. Any computer whose port is being forwarded should 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.

•

Application. Enter the name you wish to give each application.

•

Port Range (Start and End). Enter the starting and ending numbers of the port you wish to forward.

•

Protocol. Select the type of protocol you wish to use for each application:

TCP

,

UDP

, or

Both

.

•

IP Address. Enter the IP Address for the application.

Click

Enable

to enable that application.

Port Triggering

Port Triggering is used for special applications that can request a port to be opened on demand. For this feature,

the Gateway will watch outgoing data for specific port numbers. The Gateway will remember the IP address of

the computer that sends a transmission requesting data, so that when the requested data returns through the

Gateway, the data is pulled back to the proper computer by way of IP address and port mapping rules.

•

Application. Enter the name you wish to give each application.

•

Start Port and End Port. Enter the starting and ending Triggered Range numbers and the Incoming Forwarded

Range numbers of the port you wish to forward.

Click

Enable

to enable that application.

DMZ

The DMZ screen allows one local user to be exposed to the Internet for use of a special-purpose service such as

Internet gaming and videoconferencing through DMZ Hosting. DMZ hosting forwards all the ports for one

computer at the same time, which differs from Port Range Forwarding, which can only forward a maximum of 10

ranges of ports.

DMZ Hosting

. This feature allows one local user to be exposed to the Internet for use of a special-purpose

service such as Internet gaming and videoconferencing. To use this feature, select

Enabled

. To disable DMZ ,

select

Disabled

.

DMZ Host IP Address

. To expose one computer, enter the computer’s IP address. To get the IP address of a

computer, refer to

Appendix D: Finding the MAC Address and IP Address for Your Ethernet Adapter

.

QOS

Quality of Service (QoS) ensures better service to high-priority types of network traffic, which may involve

demanding, real-time applications, such as Internet phone calls or videoconferencing.

Enabled/Disabled

. To utilize QoS on the Gateway, select

Enabled

. Otherwise, keep the default,

Disabled

.

PVC QoS Priority

PVC-based QoS assigns different levels of priority, or precedence, to different PVC (Permanent Virtual Circuit).

This is useful when you have, for example, one PVC set up for traditional Internet Services (Web Browsing,

E-mail ) and another PVC set up to carry time delay sensitive data, such as VoIP or IPTV stream. And give the

second PVC a higher level priority helps to ensure the best possibility voice or picture quality. Select from

None

,

Low

,

Medium

, and

High

.

Edit list of QoS Settings

In addition to PVC-based QoS, you can assign different levels of priority to different packets based on information

in the packets. To do this, click the

Edit list of QoS Settings

button. The QoS Function screen will appear.

This screen will let you set the priority for packets selected by any of the following criteria, alone or in

combination:

•

Destination (IP address and address mask, FQDN-fully qualified domain name, or MAC address)

•

Source (IP address and address mask, or MAC address)

•

Transport protocol (TCP, UDP, or All)

•

Destination port and/or source port (if protocol is set to TCP or UDP)

•

Ethernet Type value (the value in the 13th and 14th octets of an Ethernet frame)

•

Triggering of a particular application layer gateway (FTP, TFTP, H.323, IRC, MMS, GRE, PPTP or SIP)

•

Presence of a specified IEEE 802.1D user priority marker

•

Presence of a specified IEEE 802.1Q virtual LAN (VLAN) ID

•

Packet length between specified minimum and maximum numbers of octets.

Fragment packets' size of AF and BE traffic to be equal to the size of EF traffic:

Enable this option and input a packet size to have large Assured Forwarding (medium priority) and Best Effort

(low priority) packets fragmented so they will not delay Expedited Forwarding (high priority) packets. The value

you enter should be from 68 to 1492.
