the setting.

Below are some examples of common applications and corresponding

server port they use for network access. The “NAT Port” has often the

same value as the “Server Port” value. Exceptions are made when the

same applications are used on many clients on the LAN/WLAN, where

each “Server IP” value needs to be unique and differ from the “NAT Port”

value.

Port Forwarding Example

In the following example, port forwarding is used to allow incoming access

(from the external network (Internet)) to an internal web server (on the

LAN/WLAN). The TCP protocol is used for data traffic. The NAT port 80 on

the Ericsson W3x is open and the destination computer on the LAN with

static server IP address 192.168.1.101 has appointed the server port 8080

to be used.

File and Printer Sharing

The Ericsson W3x supports local network storage and printer sharing

through the USB port. If an external USB hub is connected, the Ericsson

W3x supports connection of up to two storage devices and one printer at

the same time.

The

Sharing

page displays information about connected USB device(s):

Figure 41 - Sharing page

3.8.1

How it Works

The Ericsson W3x uses Samba (www.samba.org) as the base to

implement file and printer sharing through SMB/CIFS. SMB and CIFS are

the protocols used by Microsoft for sharing and the service is called “smb”

on the Ericsson W3x.

•

Linux Kernel auto detection of USB devices is used as part of the

automatic configuration of the storage and printer sharing. When a new

USB device (storage or printer) is detected, the Ericsson W3x

automatically creates configuration files for Samba containing the new

device. It then makes the smb service use the new configuration,

thereby sharing the USB device via the SMB/CIFS protocol. This

Page 59 / 98

Configuration and Management

process is totally automatic and there are no configuration parameters

that can be set, other than renaming the shared resources.

The Ericsson W3x uses a relatively low powered processor and is not

designed to be a multi tasking platform. This means that you may

experience problems during high load situations such as simultaneously

downloading a large file through the mobile network and printing a large

document or copying a large file to/from a shared storage device mounted

on the Ericsson W3x. Don’t expect to have full performance on all

simultaneous tasks.

3.8.1.1

Safe Removal of a USB Device

Before removing a USB device from the Ericsson W3x wait until the activity

LED (if any) on the device stops blinking or wait some 30 seconds to be

sure there is not any ongoing/remaining write operations to be made.

3.8.2

Host Name and Workgroup

All devices on the LAN/WLAN that want to access a USB shared storage

device or printer must belong to the same workgroup as the Ericsson W3x.

The following information can be changed on the

Sharing

page:

Table 20 - Sharing information

Text

Description

Host name:

The name of the Ericsson W3x on the local network.

Workgroup:

The name of the group of devices sharing the same

resources on the local network.

To change the host name or workgroup, type the new name in the

corresponding field and click

Apply

to save the settings.

For information about setting up a connection from a PC to a shared

device, follow the instruction in section 6.3.3 –

Set Up a Connection to a

Storage Device

or section 6.3.4 –

3.8.3

File Sharing

When a USB storage device is connected to the Ericsson W3x the included

files are shared with all devices on the local network (LAN/WLAN) and all

local users have full access to the shared files.

Note:

Only the first partition of the storage device will be automatically

mounted and shared through the smb service.

The file system on a shared partition needs to be of a supported type;

otherwise the automatic mounting of the device will not work. Currently the

supported types are:

•

FAT

; Microsoft legacy file system from MS-DOS with 8.3 character

filename

•

FAT32

; Microsoft Windows 95 file system based on FAT but with long

file name

•

ext2

; Second extended file system, the standard Linux file system.

•

ext3

; Like ext2, but with journaling support.

When a storage device is connected to the USB port on the Ericsson W3x,

information about the device is displayed in the “SHARED STORAGE

DEVICES” section on the

Sharing

page. If this page is open when you

connect the device, a refresh of the page may be required for the new

information to be displayed.

Description

Storage device:

The manufacturer’s name of the device.

Share name:

The name of the shared resource used when

accessing the device from a PC on the

LAN/WLAN.

To give a shared device a specific name, type a name in the corresponding

“Share name” field and click

Apply

to save the setting.

Note:

If a “Share name” includes more than 12 characters or has

embedded spaces, the share name will not be visible in Windows

95, 98 or ME clients.

To access shared files from a PC using Windows 2000 or XP, follow the

instructions in section 6.3.2- “

Access a Shared USB Storage Device

”.

3.8.4

Printer Sharing

When a printer is connected to the USB port on the Ericsson W3x, it is

automatically shared over the LAN/WLAN using SMB/CIFS protocol. The

smb service only performs protocol conversion between SMB/CIFS and the

local printer.

When a printer is connected to the USB port on the Ericsson W3x,

information about the printer is displayed in the “SHARED PRINTER”

section on the

Sharing

page. If this page is open when you connect the
