Chapter 2: Before you begin

This chapter describes how to prepare your computer network to connect to the
FSG-3 and to the internet.

2.1 Preparing Your Computers to connect to the FSG-3
To connect to the FSG-3, each computer on your network must have TCP/IP
(Transmission Control Protocol/Internet Protocol) installed and selected as its
networking protocol. If a Network Interface Card (NIC) is already installed in
your PC, then TCP/IP is probably already installed as well.

2.2 Configuring Windows 98 SE, and Me to work with the FSG-3
To be able to use your network and your FSG-3, you will need to install TCP/IP
manually and configure TCP/IP on each networked computer. Before starting,
locate your Windows CD; you may need to insert it during the TCP/IP installation
process.
2.2.1Installing the required Network Components
To install or verify the necessary components for IP networking:
1. On the Windows taskbar, click the Start button, Settings, Control Panel.
2. Double-click the Network icon.
The Network window will show you a list of installed components:

Before you begin
You must have an Ethernet adapter (NIC), the TCP/IP protocol and the Client for
Microsoft Networks installed. You do not have to remove any other network
components shown in the Network components window.

information to be able to contact other devices on the network. The FSG-3 is preconfigured to give this information automatically to all computers attached to
its LAN ports. The computers can obtain this information from the internal DHCP
server of the FSG-3. To use DHCP with the recommended default addresses,
follow these steps:
1. Start the FSG-3 and wait for it to boot. The EL ring will be on when booting
is finished. This can take up to 30 seconds. Connect all computers to the LAN
ports of the FSG-3.

2.6 Getting on the internet
If you do not have an internet account yet, but you require access to the internet,
you will need to contract with an Internet service provider (ISP) for a single-user
Internet access account. You can use both DSL or cable connections. You will
require a separate modem for your type of Internet access. These modems are
usually gotten with your internet connection from your ISP. You can then
connect the WAN port of the FSG-3 directly to the modem. To install the FSG-3
you will need some information from your ISP. Please make sure you have this
information on hand. How to setup your internet account in your FSG-3 is
described in more detail further in this manual.

Freecom FSG-3 Storage Gateway
2.7 Internet configuration information

For a single-user Internet account, your ISP supplies TCP/IP configuration information (such as IP address, subnet mask and default gateway) and VPI and VCI
multiplexing information. Your ISP may also provide other login information,
such as User Name and Password, in the case where the PPPoE or PPPoA protocol
is required. With a typical account, much of the configuration information is
dynamically assigned when your PC is first booted up while connected to the ISP,
and you do not need to know that dynamic information.

In order to share the Internet connection among several computers, your FSG3 takes the place of the single computer, and you need to configure it with the
TCP/IP information that the single computer would normally use. When the
FSG’s WAN port is connected to the modem, the FSG-3 appears to be a single
computer to the ISP. The gateway then allows the computers on the local
network to use a single user account to access the Internet through the
broadband modem. The method used by the FSG-3 to accomplish this is called
Network Address Translation (NAT) or IP masquerading.
2.7.1 Login Protocols
Some ISPs require a special login protocol, in which you must enter a login name
and password in order to access the Internet. If you already log in to your Internet
account by running a program such as WinPOET or EnterNet, then your account
uses PPP over Ethernet (PPPoE).
When you configure your FSG-3, you will need to enter your login name and
password in the FSG’s configuration menus. After your network and FSG-3 are
configured, the FSG-3 will perform the login task when needed, and you will no
longer need to run the login program from your PC. It is not necessary to
uninstall the login program.
2.7.2 Account Information
Unless these items are dynamically assigned by the ISP, your ISP should give you
the following basic information for your account:
•

An IP address and subnet mask

•

A gateway IP address, which is the address of the ISP’s router

•

One or more domain name server (DNS) IP addresses

•

Host name and domain suffix

For example, your account’s full server names may look like this:
mail.xxx.yyy.com
In this example, the domain suffix is xxx . yyy . com.

Before you begin
If any of these items are dynamically supplied by the ISP, your gateway
automatically acquires them. If an ISP technician configured your computer
during the installation of the broadband modem, or if you configured it using
instructions provided by your ISP, you need to copy configuration information
from your computer’s Network TCP/IP Properties window (or Macintosh TCP/IP
Control Panel) before reconfiguring your computer for use with the FSG-3. These
procedures are described next.

GB

2.7.3 Obtaining ISP Configuration Information (Windows)
If you were using your computer directly attached to your modem to access the
internet, you may need to collect configuration information from your computer so that you can use this information when you configure the FSG-3. If your
ISP provided this information to you on paper or provides the configuration data
dynamically, you do not require this information.
To get the information you need to configure the FSG-3 for Internet access:
1. On the Windows taskbar, click the Start button, point to Settings, and then
click Control Panel.
2. Double-click the Network icon. The Network window opens, which displays
a list of installed components.
3. Select TCP/IP, and then click Properties. The TCP/IP Properties dialog box
opens.
4. Select the IP Address tab. If an IP address and subnet mask are shown, write
down the information. Now click on "Obtain an IP address automatically".
If no address is present, your account uses a dynamically-assigned IP address
and you do not need any more information. Please close the dialog and
continue installing your computer and FSG-3.
5. Select the Gateway tab. If an IP address appears under Installed Gateways,
write down the address. This is the ISP’s gateway address. Select the address
and then click Remove to remove the gateway address.
6. Select the DNS Configuration tab. If any DNS server addresses are shown,
write down the addresses. If any information appears in the Host or Domain
information box, write it down. Click Disable DNS.
7. Click OK to save your changes and close the TCP/IP Properties dialog box. You
are returned to the Network window.
8. Click OK.
9. Reboot your PC at the prompt. You may also be prompted to insert your
Windows CD.

Freecom FSG-3 Storage Gateway
2.7.4 Obtaining ISP Configuration Information (Macintosh)

If you were using your computer directly attached to your modem to access the
internet, you may need to collect configuration information from your computer so that you can use this information when you configure the FSG-3. If your
ISP provided this information to you on paper or provides the configuration data
dynamically, you do not require this information. To get the information you
need to configure the gateway for Internet access:

1. From the Apple menu, select Control Panels, then TCP/IP. The TCP/IP Control
Panel opens, which displays a list of configuration settings. If the "Configure"
setting is "Using DHCP Server", your account uses a dynamically-assigned IP
address and you do not need any more information. Please close the dialog
and continue installing your computer and FSG-3.
2. If an IP address and subnet mask are shown, write down the information.
3. If an IP address appears under Router address, write down the address. This
is the ISP’s gateway address.
4. If any Name Server addresses are shown, write down the addresses. These are
your ISP’s DNS addresses.
5. If any information appears in the Search domains information box, write it
down.
6. Change the "Configure" setting to "Using DHCP Server".
7. Close the TCP/IP Control Panel.

2.8 Restarting the Network
Once you’ve setup your computers to work with the FSG-3, you must reset the
network for the devices to be able to communicate correctly.
1. Turn off the FSG-3 if it was on, and then turn it on again and wait for the FSG3 to restart (This can take up to 30 seconds).
2. Restart any computer connected to the FSG-3.

2.9 Ready for Configuration
After configuring all of your PCs for TCP/IP networking and connecting them to
the local network of your FSG-3, you are ready to access and configure the FSG-3.

To configure the FSG-3, your computer needs to be connected
directly to a LAN port of the FSG-3. DHCP must be enabled in the
TCP/IP settings of the PC! For more information, you can read the
" chapter. Use this PC to login to the FSG-3
"Before you begin"
configuration menu.

5.1 How to reach the configuration menu
There are several methods of reaching the configuration screen. First, as
described in the "Freecom Storage Gateway Assistant" chapter, you can easily
find and configure the machine using the Freecom Storage Gateway Assistant.
Second, you can use a browser to go to the online configuration pages. Please
make sure your PC is set to DHCP and connected to one of the three LAN ports.
You can use a standard web browser such as Firefox or Internet Explorer to go
to the FSG-3 configuration pages. The FSG-3 is located on
http://192.168.1.1
Please type the above IP address into the browser address window and press
enter. You can also type
//FSG_NAME
(Factory default is //FSG)
in the browser address window and you will be brought to the FSG-3 frontpage
as well. Click on the configuration button and you will be asked for a username
and password. The standard administrator is:
Administrator username:
admin
Administrator password:
admin
Be carefull, the username and password are CaSe SeNsAtIvE. This means
"Admin" is someone else then "admin". Please change the factory default
password as soon as possible!

Configuration
5.2 First steps

Even though you can start using the FSG-3 with no setup at all, you might want
to configure some of the items of the FSG-3 to benefit from the full potential of
the product. To start using the full potential of the FSG-3, several items will have
to be configured.

1. Changing the administrator password
2. WAN or internet connection (If available).
3. Date and time.
4. Users, groups and folders.
5. Connection methods.
It is also wise to go on the internet to the Freecom site or OpenFSG site and see
there if you are using the latest firmware update. Firmware updates solve
problems and many new features are being added with each new release!

5.3 Changing the administrator password
For security reasons it is highly recommended you change the admin password.
To do this:
•

Go to the configuration website of your FSG-3.

•

Click on the Security section in the left menu.

•

Click on the Administrator section in the left menu.

•

Type in the old password and then enter the new password twice.

•

Press "Change password"

5.4 WAN or internet connection setup
Next to using the FSG-3 as a standalone router and NAS and connecting
computers and switches and routers to the LAN ports, there is also the option of
connecting the FSG-3 WAN port to an existing router or straight to an internet
modem.

Freecom FSG-3 Storage Gateway
5.4.1 The FSG-3 WAN port connected to a router

To first set up the FSG-3, your computer will have to be connected to a LAN port
of the FSG-3. This can be changed in a later stage in the services / SMB section.

Connecting the hardware
1. Connect a RJ45 cable to a LAN port of your router.
2. Connect the other side of the cable with the WAN port of the Freecom
Storage Gateway.
3. After setting up the FSG-3, network PCs can be connected to the FSG-3 and
your router.
Setting up the FSG-3
1. Login to the configuration menu of your FSG-3
2. Go to Connections -> LAN and select an IP address for the FSG-3.
To avoid IP address conflicts in your network, make sure that the
LAN IP address of your FSG-3 and the LAN IP address of your router
are different.
3. Go to Connections -> WAN and select "Use fixed IP address". This will allow
you to easily set up access to your FSG-3 from other locations such as the
internet. Use the following settings:
IP address: Enter an IP address which is in the address range of your router,
e.g. if your router IP address 192.168.2.1, enter 192.168.2.2 for your FSG-3.
This IP address can be used to access the FSG-3 from anywhere in
your local network.
Subnet Mask: Enter the subnet mask of your router, e.g. 255.255.255.0.
Default Gateway: IP address of your router, e.g. 192.168.2.1.

Configuration

GB
5

4. Go to Connections -> WAN Options and activate "Open SMB/CIFS on WAN
port"

5. To have HTTP and FTP access from outside to the FSG-3, you have to forward
port 80 (HTTP) and port 21 (FTP) to the FSG-3 IP address. This is the fixed WAN
IP address assigned in step 3 (e.g. 192.168.2.2).

Freecom FSG-3 Storage Gateway
See the manual of your router for detailed information how to forward ports.

Make sure to activate the options "Open HTTP server for the
outside"/ "Open FTP server for the outside" under Services in the
FSG-3 configuration menu.

Remark: DynDNS options of the FSG-3 will not work. Please use
the DynDNS options of your router.

5.4.2 The FSG-3 WAN port connected to a modem
To use the internet through your FSG-3, you will need to setup the FSG-3 with
the configuration information provided by your ISP. This information is described in detail in the "Getting on the internet" section of the "Before you
begin" chapter.
To configure your FSG-3 with this information, you should:
•

Go to the configuration website of your FSG-3.

•

Click on Connections section in the left menu

•

Click on WAN in the left menu

•

If the IP information is gotten dynamically, check that the DHCP client is set,
all should be done now otherwise:

•

Click on the "Run DSL client" radio button

•

Fill in the information you have received from your ISP (See the "WAN
Connection" and "WAN Options" section for more details)

•

Press Apply.

•

Save your configuration.

•

You can test the connection by starting your internet browser and seeing if
you can reach your favorite internet page or by looking at the info menu and
the WAN item in the FSG-3 configuration website.
Remark: Establishing a DSL connection with ISP might take some
time.

Configuration
5.5 Set the Date and Time

To set the date and time on the FSG-3, you should:
•

Go to the configuration website of your FSG-3.

•

Click on Hardware section in the left menu

•

Click on Date & Time in the left menu

•

Set the date and time

•

Press apply

5.6 Setting up users, groups and folders
Your FSG-3 is setup with 2 standard accounts. The admin account and the guest
account.
5.6.1 The admin account
The admin account has access to all parts of the FSG-3 including the configuration. Because it has no limits, it can be dangerous to use this account in day to
day use. There are nolimitations on what you can delete for instance. You might
accidentally delete something that is required for the FSG-3 to run. Of course you
can still recover your FSG-3 using the FSG Assistant, but we recommend for this
reason to create a normal user account (or use the guest account) for the day to
day business.
5.6.2The guest account
The guest account is setup to be accessible by anyone. It has its own folder where
it has all rights. If you are the only one working on the FSG-3, or you do not mind
sharing your files with any other users of the FSG-3, you can use this account.
If you are working in an environment where some of your files are private, we
suggest you create an account per user. All users will still have access to the guest
account, even if they log in with their own user name (the shared folder) but they
will now also have their own private storage space. The admin account always
has rights to all folders.
If you want to have folders where some have rights and some not, you can use
the groups and folders settings described later in this chapter.
Since the guest account is open to anyone, it can also be a security risk if you open
any services (FTP, SMB, SSH, HTML) to the internet or even for your internal
network.

Freecom FSG-3 Storage Gateway
5.6.3 Creating a new account

How to create a new account is described in the "Users" section of the
"Configuration options explained" chapter.

When you create an account, a folder with the same name is automatically
created. Only the user with that name can access that folder. You can give others
rights to these folders by
•

Adding users to the folders in the folder dialog

•

Creating groups with rights to these folders and adding several users to these
groups.

You cannot create accounts with the same login name. You can create as many
accounts as you like, but remember the storage capacity of the FSG-3 will
eventually run out.
5.6.4 Creating a new group
If you have a large amount of folders and users, and some folders should be
accessible to some users but not to others, it can be easy to group the users who
have access to a certain folder. You will only have to add or remove a user once
from a group to give or remove access rights to all the folders the group has
access to for that user.
How to create a new group is described in the "User Groups" section of the
"Configuration options explained" chapter.
5.6.5 Creating a new folder
Even though all users get their own private folder, you may want to create other
folders shared by more then one user.
How to create a new folder is described in the "Folders" section of the
"Configuration options explained" chapter.
Once you have created a folder, you can add users or groups to that folder to give
users access rights.

5.7 Setting up multiple connection methods
The default setup of the FSG-3 only allows windows file sharing (SMB) and HTML
access through a LAN port. In the case you want to have more services available
(such as FTP), or when you connect the FSG-3 to an existing router, or even to the
internet, you will need to configure the services to be available. Remember, each
service you turn on or open to the outside is a potential security risk. We are not
aware of any security threats at the moment, but we cannot predict what will
be found in the future. You should only turn on services or open them to the
outside when you really need them.

Configuration
Please look at the "Configuration options explained" chapter and especially at
the sections about opening these services to the outside (All in the Services
menu):

energy. If the FSG-3 is not used for a long time, it is more beneficial to spin down
the hard drive. This uses less power and creates less noise and heat. It also
prolongs the lifetime of the hard disk. After the disk has been spun down, the
first access will take longer, since the hard disk will have to start spinning again.
You can set the time it takes for the hard drive to spin down after last use. If you
do not want the disk to spin down, please set this to 0.

Freecom FSG-3 Storage Gateway
Chapter 11: Troubleshooting

This chapter gives information about troubleshooting your Freecom Storage
Gateway. After each problem description, instructions are provided to help you
diagnose and solve the problem.

Basic Functioning
If you are experiencing problems, please check if
•

Both the FSG-3 and the PC are powered on.

•

The Ethernet Cable is securely fastened to both devices.

•

The Ethernet Cable is not damaged, to verify this try using another Ethernet
Cable.

After you turn on the power of the FSG-3, the following sequence of events
should occur:
1. When power is first applied, verify that the Power LED is on.
2. Verify that the Power LED starts blinking within a few seconds, indicating
that the self-test procedure is running.
3. After approximately 20 seconds, verify that:
a. The Power LED is OFF and the EL Ring is ON.
b. The LAN port LEDs are lit for any local ports that are connected.
If a port’s LED is lit, a link has been established to the connected device. If a LAN
port is connected to a 100 Mbps device, verify that the port’s LED is green. If the
port is 10 Mbps, the LED will be amber.
If any of these conditions does not occur, refer to the appropriate following
section.
PWR LED Not On
If the PWR and other LEDs are off when your FSG-3 is turned on:

•

Make sure that the power cord is properly connected to your gateway and
that the power supply adapter is properly connected to a functioning power
outlet.

•

Check that you are using the 12 V AC power adapter supplied by Freecom for
this product.

•

Try pressing the power button longer

•

If the error persists, you have a hardware problem and should contact
technical support.

Troubleshooting
Troubleshooting the Web Configuration Interface

If you are unable to access your FSG’s Web Configuration interface from a PC on
your local network, check the following:
•

Check the Ethernet connection between your PC and the FSG-3 using the
ping utility as described in this chapter.

•

Test the Ethernet cable by using a different cable.

•

Make sure your PC’s IP address is on the same subnet as the FSG-3. If you are
using the recommended addressing scheme, your PC’s address should be in
the range of 192.168.1.2 to 192.168.1.254. Refer to "Verifying TCP/IP Properties (Windows)" or "Verifying TCP/IP Properties (Macintosh)" to find your
PC’s IP address. Follow the instructions to configure your PC.

Attention: If your PC’s IP address is shown as 169.254.x.x:
Recent versions of Windows and MacOS will generate and assign
an IP address if the computer cannot reach a DHCP server. These
auto-generated addresses are in the range of 169.254.x.x. If your
IP address is in this range, check the connection from the PC to the
FSG-3 and reboot your PC.
•

If your FSG’s IP address has been changed and you don’t know the current IP
address, clear the FSG’s configuration to factory defaults. This will set the
FSG’s IP address to 192.168.1.1.
This procedure is explained in "Restoring the Default Configuration and
Password" in this chapter.

•

Make sure your browser has JavaScript enabled.

•

Try quitting the browser and launching it again.

•

Make sure you are using the correct login information. The factory default
login name is admin and the password is admin. Make sure that CAPS LOCK
is off when entering this information. Both the username and password are
case sensitive!

If the FSG-3 does not save changes you have made in the Web Configuration
Interface, check the following:
•

When entering configuration settings, be sure to click the APPLY button
before moving to another menu or tab, or your changes are lost.
Click the Refresh or Reload button in the Web browser. The changes may
have occurred, but the Web browser may be caching the old configuration.

Freecom FSG-3 Storage Gateway
Troubleshooting the ISP Connection

If your FSG-3 is unable to access the Internet, you should first determine whether
you have an ADSL link with the service provider. The state of this connection is
indicated with the WAN LED on the modem you were provided with your ADSL
account.

If disconnecting telephones does not result in a green WAN LED the problem
may be one of the following:
•

Check that the telephone company has made the connection to your line and
tested it.

•

Verify that you are connected to the correct telephone line. If you have more
than one phone line, be sure that you are connected to the line with the ADSL
service.

Obtaining a WAN IP Address
If your FSG-3 is unable to access the internet, and your WAN LED is off or blinking
blue, you should determine whether the FSG-3 is able to obtain a WAN IP address
from the ISP. Unless you have been assigned a static IP address, your FSG-3 must
request an IP address from the ISP. You can determine whether the request was
successful using the browser interface.
To check the WAN IP address from the browser interface:
1. Launch your browser and select an external site such as www.freecom.com
2. Access the Main Menu of the FSG-3 at http://192.168.1.1 and click on the
configuration icon.
3. Login using the "admin" account and your admin password.
4. Under the WAN section in the information menu check that an IP address is
shown for the WAN Port. If 0.0.0.0 is shown, your FSG-3 has not obtained an
IP address from your ISP. If your FSG-3 is unable to obtain an IP address from
the ISP, the problem may be one of the following:

•

Your ISP may require a login program. Ask your ISP whether they require PPP
over Ethernet (PPPoE) login.

•

If you have selected a login program, you may have incorrectly set the Service
Name, User Name and Password. See "Troubleshooting PPPoE", below.

•

Your ISP may check for your PC’s host name. Assign the PC Host Name of your
ISP account to the FSG-3 in the WAN section of the Connections menu.

•

Your ISP only allows one MAC address to connect to Internet, and may check
for your PC’s MAC address. In this case, inform your ISP that you have bought
a new network device, and ask them to use the FSG’s MAC address. You can
also use the MAC addresses cloning section in WAN options in the connections configuration screen to masquerade as the MAC address of your PC.

Troubleshooting
Troubleshooting PPPoE

The PPPoE connection can be debugged as follows:
1. Access the Main Menu of the FSG-3 configuration at http://192.168.1.1.

2. Click on the configuration icon.
3. Under the log files section of the information menu, look at all the logs.
4. If all of the steps indicate "OK" then your PPPoE connection is up and
working.
If any of the steps indicates "Failed", you can attempt to reconnect by clicking
"Connect". The FSG-3 will continue to attempt to connect indefinitely.
If you cannot connect after several minutes, you may be using an incorrect
Service Name, User Name or Password. There also may be a provisioning
problem with your ISP.
Attention: Unless you connect manually, the FSG-3 will not authenticate using PPPoE until data is transmitted to the network.

Troubleshooting Internet Browsing
If your computer can obtain an IP address but you are unable to load any web
pages from the Internet, your PC may not recognize any DNS server addresses.
A DNS server is a machine on the Internet that translates Internet names (such
as www addresses) to numeric IP addresses that computers can work with.
Typically your ISP provides the addresses of one or two DNS servers for your use.
You can verify the DNS address of your computer as described in "Verifying TCP/
IP Properties". If you are using the default, it should be the same as your gateway
address, which is your FSG-3. You can check what DNS names your FSG-3 is using
in the Information menu.
You can also configure your PC manually with DNS addresses. Your operating
system documentation should describe how to do this.
Does your PC have the FSG-3 configured as its TCP/IP gateway?
If your PC obtains its information from the FSG-3 by DHCP, reboot the PC and
verify the gateway address as described in "Verifying TCP/IP Properties".
Troubleshooting a TCP/IP Network Using a Ping Utility
Most TCP/IP devices such as computers contain a ping utility that sends an echo
request packet to the designated device. The device then responds with an echo
reply. Troubleshooting a TCP/IP network is made very easy by using the ping
utility in your PC or workstation.

Freecom FSG-3 Storage Gateway
Testing the LAN Path to Your Gateway

You can ping the FSG-3 from your PC to verify that the LAN path to your FSG-3
is set up correctly.

To ping the FSG-3 from a PC running Windows 98 SE or later:
1. From the Windows toolbar, click the Start button and select Run.
2. In the field provided, type Ping followed by the IP address of the gateway,
as in this example: ping 192.168.1.1
3. Click OK. You should see a message like this one:
Pinging with 32 bytes of data
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
Request timed out.
If the path is not functioning correctly, you could have one of the following
problems:
Wrong physical connections
•

Make sure the LAN LNK/ACT LED is on. If the LNK/ACT LED is off, follow the
instructions in Troubleshooting the Web Configuration Interface.

•

Check if your Ethernet cable is broken by using a different one.

Wrong network configuration
•

Verify that the Ethernet card driver software and TCP/IP software are both
installed and configured on your PC or workstation.

•

Verify that the IP address for your FSG-3 and your workstation are correct and
that the addresses are on the same subnet. In the IP addresses of your PC and
your FSG-3, A.B.C.x, A, B and C should be the same for both the PC and FSG-3.

Testing the Path from Your PC to a Remote Device
After verifying that the LAN path works correctly, test the path from your PC to
a remote device.

•

Go to start

•

Click on the run menu

•

Type: PING -n 10 where is the IP address of a remote
device such as your ISP’s DNS server.

Troubleshooting
If the path is functioning correctly, replies as in the previous section are
displayed. If you do not receive replies:
•

•

Check that your PC has the IP address of your gateway listed as the default
gateway. If the IP configuration of your PC is assigned by DHCP, this
information will not be visible in your PC’s Network Control Panel. Go to the
Run… window and run winipcfg. Verify that the IP address of the FSG-3 is
listed as the default gateway as described in Verifying TCP/IP Properties.

Check to see that the network address of your PC (the portion of the IP
address specified by the netmask) is different from the network address of
the remote device.

Restoring the Default Configuration and Password
Resetting the FSG-3 to its factory defaults changes the FSG’s administration
password to "admin" and the IP address to 192.168.1.1. You can erase the
current configuration and restore factory defaults in two ways:
•

Use the Erase function of the Web Configuration as described in the "Reset
Configuration" part of the "Hardware menu" section of the "Configuration
options explained" chapter.

•

Press the Reset button on the rear panel of the gateway with a long object
for several seconds. Use this method for cases when the administration
password or IP address is not known.

Using the Default Reset button
To reset the factory default configuration settings, you can use the reset button
on the rear of the FSG-3.
1. Press and hold the Reset button (about 10 seconds).
2. Release the Reset button and wait for the FSG-3 to reboot.
Problems with Date and Time
The log menu in the information section displays the current date and time of
day. The FSG-3 has a battery powered real time clock that you initially tell the
date and time. Each entry in the log files is stamped with the date and time of
day. Problems with the date and time function can include:
•

Date shown is January 1, 2000
Cause: The FSG-3 has not yet successfully been set up. Please set the date and
time in the Hardware / Date&Time section. If you have just completed
configuring the FSG-3, wait at least five minutes and check the date and time
again.

Freecom FSG-3 Storage Gateway
•

Time is off by one hour
Cause: The FSG-3 does not automatically sense Daylight Savings Time. Please
change the time in the Hardware / Date&Time section.

Appendix
Networks and Routing Basics

This chapter provides an overview of IP networks, routing, and firewalls. This is
by no means a complete overview! If you are looking for more information, you
can use your favorite search engine to find information on the internet about
the internet. Suffice to say, there is plenty.
Basic Router Concepts
Even though the amount of bandwidth in your local area network (LAN) can be
provided easily and relatively inexpensively, the price of the connection to the
internet is much higher. Because of this expense, Internet access is usually
provided by a slower-speed wide-area network (WAN) link such as a cable or DSL
modem. To use this WAN link efficiently, a mechanism must be in place for
selecting and transmitting only the data traffic meant for the Internet. The
function of selecting and forwarding this data is performed by a router.
What is a Router?
A router splits the information meant for your network and meant for other
networks, so the available bandwidth is used efficiently. The router sends data
based on network layer information in the data and on routing tables maintained by the router. The routing tables are built by gathering and exchanging
information with other routers in the network. The router builds up a logical
picture of the overall network. Using this information, the router chooses the
best path for forwarding network traffic. Routers vary in performance and scale,
number of routing protocols supported, and types of physical WAN connection
they support.
Routing Information Protocol
One of the protocols used by a router to build and maintain a picture of the
network is the Routing Information Protocol (RIP). Using RIP, routers periodically
update one another and check for changes to add to the routing table.
IP Addresses and the Internet
For a computer to communicate with other computers and Web servers on the
Internet, it must have a unique IP address. An IP address (IP stands for Internet
Protocol) is a unique number that identifies the location of your computer on a
network.
Basically, it works like your street address — as a way to find out exactly where
you are and deliver information to you. The IP address is written as 4 numbers
between 0 and 256, such as "192.168.0.12".

Freecom FSG-3 Storage Gateway
Domain Name Server

Since this computer address is not very easy to read, there is a second system on
the internet called DNS (Domain Name System) which translates human readable names such as "www.sharemydisk.com" to computer readable names such
as "82.161.11.206". Everyone on the internet must have an IP address. You don’t
need the human readable name, but it helps tremendously if you want others
to find you, such as the case when you have a web server running or want to show
the pictures on your computer to your friends.
Many large organizations, such as ISPs, maintain their own DNS servers and allow
their customers to use the servers to look up addresses.
The internet address classes
Blocks of addresses are assigned to organizations by the Internet Assigned
Numbers Authority (IANA). Individual users and small organizations may obtain
their addresses either from the IANA or from an Internet service provider (ISP).
You can contact IANA at www.iana.org.
The IANA gives out ranges of IP addresses based on classes. There are five
standard classes of IP addresses. The five address classes are:
Class A
Class A addresses can have up to 16,777,214 hosts on a single network. They use
an eight-bit network number and a 24-bit node number. Class A addresses are
in this range: 1.x.x.x to 126.x.x.x.
Class B
Class B addresses can have up to 65,354 hosts on a network. A Class B address uses
a 16-bit network number and a 16-bit node number. Class B addresses are in this
range: 128.1.x.x to 191.254.x.x.
Class C
Class C addresses can have 254 hosts on a network. Class C addresses use 24 bits
for the network address and eight bits for the node. They are in this range:
192.0.1.x to 223.255.254.x.
Class D
Class D addresses are used for multicasts (messages sent to many hosts). Class D
addresses are in this range:
224.0.0.0 to 239.255.255.255.

Appendix
Class E

Class E addresses are for experimental use.
For each unique value of the network portion of the address, the base address
of the range (host address of all zeros) is known as the network address and is
not usually assigned to a host. Also, the top address of the range (host address
of all ones) is not assigned, but is used as the broadcast address for simultaneously sending a packet to all hosts with the same network address.
Netmask
The partitioning scheme separating the different address classes can be expressed by a netmask associated with the IP address. A netmask is a 32-bit
quantity that, when logically combined (using an AND operator) with an IP
address, yields the network address. For instance, the netmasks for Class A, B,
and C addresses are 255.0.0.0, 255.255.0.0, and 255.255.255.0, respectively.
For example, the address 192.168.170.237 is a Class C IP address whose network
portion is 192.168.170. When combined (using an AND operator) with the Class
C netmask, as shown here, only the network portion of the address remains:
11000000 10101000 10101010 11101101 (192.168.170.237)
combined with:
11111111 11111111 11111111 00000000 (255.255.255.0)
Equals:
11000000 10101000 10101010 00000000 (192.168.170.0)
As a shorter alternative to dotted-decimal notation, the netmask may also be
expressed in terms of the number of ones from the left. This number is appended
to the IP address, following a backward slash ( / ), as "/n." In the example, the
address could be written as 192.168.170.237/24, indicating that the netmask is
24 ones followed by 8 zeros.

Freecom FSG-3 Storage Gateway
Subnet Addressing

You can see that even with a Class C address, there are a large number of hosts
per network. It would be a very inefficient use of the amount of IP addresses to
supply every LAN with so many IP addresses. A smaller office LANs does not have
that many devices. A more efficient technique is known as subnet addressing.
Subnet addressing allows us to split one IP network address into smaller multiple
physical networks known as subnetworks. Some of the node numbers are used
as a subnet number instead. A Class B address gives us 16 bits of node numbers
translating to 64,000 nodes. Most organizations do not use 64,000 nodes, so
there are free bits that can be reassigned. Subnet addressing makes use of those
bits that are free.
A Class B address can be effectively translated into multiple Class C addresses. For
example, the IP address of 172.16.97.235 would be interpreted as IP network
address 172.16, subnet number 97, and node number 235. In addition to
extending the number of addresses available, subnet addressing provides other
benefits. Subnet addressing allows a network manager to construct an address
scheme for the network by using different subnets for other geographical
locations in the network or for other departments in the organization.
Although the preceding example uses the entire third octet for a subnet address,
note that you are not restricted to octet boundaries in subnetting. To create
more network numbers, you only need to shift some bits from the host address
to the network address. For instance, to partition a Class C network number
(192.68.135.0) into two, you shift one bit from the host address to the network
address. The new netmask (or subnet mask) is 255.255.255.128. The first subnet
has network number 192.68.135.0 with hosts 192.68.135.1 to 129.68.135.126,
and the second subnet has network number 192.68.135.128 with hosts
192.68.135.129 to 192.68.135.254.
Attention: The number 192.68.135.127 is not assigned because it
is the broadcast address of the first subnet. The number
192.68.135.128 is not assigned because it is the network address
of the second subnet.
Freecom strongly recommends that you configure all hosts on a LAN segment to
use the same netmask for the following reasons:
•

So that hosts recognize local IP broadcast packets
When a device broadcasts to its segment neighbors, it uses a destination
address of the local network address with all ones for the host address. In
order for this scheme to work, all devices on the segment must agree on
which bits comprise the host address.

•

So that a local router or bridge recognizes which addresses are local and
which are remote Private IP Addresses

Appendix
If your local network is not connected to the Internet (for example, when using
NAT), you can assign any IP addresses to your computers without problems. But
to prevent problems and ease configuration, the IANA has reserved the following three blocks of IP addresses specifically for private networks:

10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
We recommend that you choose your private network number from this range.
The DHCP server of the FSG-3 is preconfigured to automatically assign private
addresses.
For more information about address assignment, refer to RFC 1597, Address
Allocation for Private Internets, and RFC 1466, Guidelines for Management of IP
Address Space. The Internet Engineering Task Force (IETF) publishes RFCs on its
Web site at www.ietf.org.
The IP address shortage
The Internet has grown larger than anyone ever imagined it could be. Although
the exact size is unknown, the current estimate is that there are about 100
million hosts and more than 350 million users actively on the Internet. In fact, the
rate of growth has been such that the Internet is effectively doubling in size each
year.
When IP addressing first came out, everyone thought that there were plenty of
addresses to cover any need. Theoretically, you could have 4,294,967,296 unique
addresses (232). The actual number of available addresses is smaller (somewhere
between 3.2 and 3.3 billion) because of the way that the addresses are separated
into classes, and because some addresses are set aside for multicasting, testing
or other special uses.
With the explosion of the Internet and the increase in home networks and
business networks, the number of available IP addresses is simply not enough.
The obvious solution is to redesign the address format to allow for more possible
addresses. This is being developed (called IPv6), but will take many years to
implement because it requires modification of the entire infrastructure of the
Internet.
There are 2 systems in place now to help bring down the shortage of IP addresses.

Freecom FSG-3 Storage Gateway
DHCP

First, most users today have a dynamically given IP address or DHCP address from
their provider. This means that the IP address given to you can change over time.
This allows the provider to use the IP address for more then one person or device,
since people are often online at different times. Optimal usage of IP addresses
is guaranteed.
Your FSG-3 gives its internal addresses to your computers in the same way. For
the DNS (Domain Name System) it is difficult to translate your domain name
"www.yourname.sharemydisk.com" to your IP address if your IP address keeps
changing.
The system needs to be updated each time your IP address changes. Hence
Dynamic DNS (DDNS) programs. These programs check the latest IP address and
update the DNS system accordingly.
Multiple internal but only one external IP address
A second way to overcome this is to have a single device act on behalf of several
other devices. Routers are typical examples. You have several PCs connect to the
router, but only the router to the Internet. From an internet perspective, there
is only one address. This scheme offers the additional benefit of simple firewalllike protection because the internal LAN addresses are not available to the
Internet through the translated connection. All incoming inquiries are filtered
out by the router. This filtering can prevent intruders from probing your system.
However, using port forwarding, you can allow one PC (for example, a Web
server) on your local network to be accessible to outside users.
This works like a receptionist at a large office. Nobody knows your number; they
all call the main number of the office and are then forwarded by the receptionist
to you.
So how does the receptionist know what number to forward the call too? The
caller tells the receptionist what name to look for and the receptionist has a listof
names and numbers at her disposal so she can translate the name to the phone
extension she needs.
On the Internet, it works exactly the same. NAT (RFC 1631) or Network Address
Translation allows a single device, such as a router, to act as an agent between
the Internet (or "public network") and a local (or "private") network. This means
that only a single, unique IP address is required to represent an entire group of
computers.

Appendix
Network Address Translation

When you visit a website via your computer, your router, or more specifically
your NAT, remembers which computer on the internal network asked for the
information. When the information (in this case the website you asked for)
comes back, the router knows which computer on the internal network to send
the information to. This is Network Address Translation or NAT.
Developed by Cisco, Network Address Translation is used by a device (firewall,
router or computer) that sits between an internal network and the rest of the
world. For more information about IP address translation, refer to RFC 1631, The
IP Network Address Translator (NAT).
Hosting a server
What If I want to host a server?
For others to be able to view your pictures on your computer, you need to run
some type of service or server. A web server such as apache will allow others to
securely watch the pictures or files on your site. But how does the NAT of your
router know this time to which computer to forward the information?
Since the request comes from the internet, most routers are setup to disallow any
traffic going into the internal network. (Firewall protection) In this case, since we
want people to be able to see our pictures, we want the router to forward this
information. We have to tell the router to do this.
Someone calling from the internet asks your router for a certain "port". This is
the same as someone calling the receptionist and requesting a certain person by
name. Ports are displayed as numbers but invariably map to pre described
services. For instance, when someone requests a web page, they always ask for
the service on port 80, the web server. Through NAT, it is possible to "map" a
certain request for a service (a request for a port) to a certain PC on the internal
network.

MAC Addresses and Address Resolution Protocol

An IP address alone cannot be used to deliver data from one LAN device to
another. To send data between LAN devices, you must convert the IP address of
the destination device to its media access control (MAC) address. Each device on
an Ethernet network has a unique MAC address, which is a 48-bit number
assigned to each device by the manufacturer. The technique that associates the
IP address with a MAC address is known as address resolution. Internet Protocol
uses the Address Resolution Protocol (ARP) to resolve MAC addresses. If a device
sends data to another station on the network and the destination MAC address
is not yet recorded, ARP is used. An ARP request is broadcast onto the network.
All stations on the network receive and read the request. The destination IP
address for the chosen station is included as part of the message so that only the
station with this IP address responds to the ARP request. All other stations
discard the request.
The station with the correct IP address responds with its own MAC address
directly to the sending device. The receiving station provides the transmitting
station with the required destination MAC address. The IP address data and MAC
address data for each station are held in an ARP table. The next time data is sent,
the address can be obtained from the address information in the table.
Ethernet Cabling
There are two different types of cabling for Ethernet networks. Originally they
used thick or thin coaxial cable, but most installations currently use unshielded
twisted pair (UTP) cabling. The UTP cable contains eight conductors, arranged in
four twisted pairs, and terminated with an RJ45 type connector. There are 2
types of RJ-45 cables available today, the Media Dependent Interface (MDI)
cable and the Media Dependent Interface - Crossover (MDI-X) cable. The first
cable is used to connect routers to PCs and the second to connect PCs directly to
PCs. The sent and receive wires are switched from beginning to end in the
crossover cables. Some Ethernet switch products, such as the FSG-3, are able to
sense the polarity of a connection and automatically adapt to the proper cabling
type.
Cable Quality
A twisted pair Ethernet network operating at 10 Mbits/second (10BASE-T) will
often tolerate low quality cables, but at 100 Mbits/second (10BASE-Tx) the cable
must be rated as Category 5, or "Cat 5", by the Electronic Industry Association
(EIA). This rating will be printed on the cable jacket. A Category 5 cable will meet
specified requirements regarding loss and crosstalk. In addition, there are
restrictions on maximum cable length for both 10 and 100 Mbits/second
networks.
