Select

Advanced > Advanced Setup > Port Forwarding/Port Triggering

.

The Port Forwarding/Port Triggering screen displays.

5.

Select the

Port Triggering

radio button.

6.

In the

Port Triggering Timeout

field, enter a value up to 9999 minutes.

This value controls how long the inbound ports stay open when the gateway detects no

activity. This value is required because the gateway cannot detect when the application

terminates.

Application Example: Port Triggering for Internet Relay Chat

Some application servers, such as FTP and IRC servers, send replies to multiple port

numbers. Using port triggering, you can tell the gateway to open more incoming ports when a

particular outgoing port starts a session.

An example is Internet Relay Chat (IRC). Your computer connects to an IRC server at

destination port 6667. The IRC server not only responds to your originating source port, but

also sends an “identify” message to your computer on port 113. Using port triggering, you can

tell the gateway, “When you initiate a session with destination port 6667, you must also allow

incoming traffic on port 113 to reach the originating computer.” The following sequence

shows the effects of this port triggering rule:

1.

You open an IRC client program to start a chat session on your computer.

2.

Your IRC client composes a request message to an IRC server using a destination port

number of 6667, the standard port number for an IRC server process. Your computer then

sends this request message to your gateway.

3.

Your gateway creates an entry in its internal session table describing this communication

session between your computer and the IRC server. Your gateway stores the original

information, performs Network Address Translation (NAT) on the source address and port,

and sends this request message through the Internet to the IRC server.

4.

Noting your port triggering rule and observing the destination port number of 6667, your

gateway creates another session entry to send any incoming port 113 traffic to your

computer.

5.

The IRC server sends a return message to your gateway using the NAT-assigned source

port (for example, port 33333) as the destination port and sends an “identify” message to

your gateway with destination port 113.

6.

When your gateway receives the incoming message to destination port 33333, it checks its

session table to see if a session is active for port number 33333. Finding an active session,

the gateway restores the original address information replaced by NAT and sends this reply

message to your computer.

7.

When your gateway receives the incoming message to destination port 113, it checks its

session table and finds an active session for port 113 associated with your computer. The

gateway replaces the message’s destination IP address with your computer’s IP address

and forwards the message to your computer.

8.

When you finish your chat session, your gateway eventually senses a period of inactivity in

the communications and removes the session information from its session table, and

incoming traffic is no longer accepted on port numbers 33333 or 113.

Share a USB Drive Attached to the

Gateway

This chapter describes how to access and configure a USB storage drive attached to your

gateway. The USB port on the gateway can be used to connect only USB storage devices like

flash drives or hard drives, or a printer. Do not connect computers, USB modems, CD drives, or

DVD drives to the gateway USB port.

USB Drive Requirements

The gateway works with most USB-compliant external flash and hard drives. For the most

up-to-date list of USB drives that the gateway supports, visit

.

Some USB external hard drives and flash drives require you to load the drivers onto the

computer before the computer can access the USB device. Such USB devices do not work

with the gateway.

The gateway supports the following file system types for full read/write access:

•

FAT16

•

FAT32

•

NTFS

•

NTFS with compression format enabled

•

Ext2

•

Ext3

•

Ext4

Access a USB Drive on the Network

ReadySHARE lets you access and share a USB drive connected to the gateway USB port. (If

your USB drive uses special drivers, it is not compatible.)



To connect a USB drive:

Insert your USB storage drive into the USB port on the rear panel of the gateway.

If your USB drive uses a power supply, you must use it when you connect the USB drive

to the gateway.

When you connect the USB drive to the gateway USB port, it might take up to two

minutes before it is ready for sharing. By default, the USB drive is available to all

computers on your local area network (LAN).



To access the USB drive from a Mac:

1.

Select

Go > Connect to Server

.

2.

Enter

smb://readyshare

as the server address.

3.
