Next to using the FSG 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
WAN port to an existing router or straight to an internet modem.
5.1.1 Using the FSG behind a router
Note: When initially configuring the FSG, your computer needs to be
connected to one of the LAN ports on this device.
Connecting the hardware
1. Connect a RJ45 cable to a LAN port on your router.
2. Plug the other end of the cable into the WAN port on the Freecom Storage Gateway.
3. Once the FSG is configured, you can connect the network PC to the FSG or your
router.
FSG configuration
Using a fixed IP address Preparation
1. Check the 'DHCP' box under TCI/IP Settings in your computer's network settings. For
more details, refer to Appendix B in this manual.
2. Connect your PC to the FSG.
3. Open the Internet browser and start the Configuration menu for the FSG (factory
defaults: http://fsg or. http://192.168.1.1).
4. Open 'Connections' -> LAN' and select an IP address for the FSG.
To prevent conflicting IP addresses in your network, make sure the LAN
IPs for your FSG and router are different.
5. Open 'Connection' -> 'WAN' and select 'Use fixed IP address'.

Using the FSG behind a router via DHCO
1. Open 'Information' -> 'Network'. You can view the IP address assigned by the router
to your FSG under WAN Port -> IP address. If your router uses the IP address
192.168.2.1, the FSG IP address for example could be 192.168.2.100.
2. If you want to access the FSG from outside the network (e.g., over the Internet) via
HTTP (port 80) and FTP (port 21), you will need to forward these ports on your router
to the IP address assigned by the router to the FSG. In our example, you need to
forward ports 21 and 80 to the IP address 192.168.2.100. For more details on
forwarding ports, please refer to your router's manual.
3. Please make sure that 'Services' -> 'HTTP Server' -> 'Open HTTP server to the outside'
and 'access for configuration pages from the outside” / 'FTP Server' 'open FTP server

5.2 Dynamic DNS
GB
A DynDNS entry allows you to access a computer using a dynamic IP address at any time
under the same domain name. To do so, you first need to register with a DynDNS service.
It updates the modified IP addresses and forwards this to the domain name. This enables
you to be reached at one single domain name at any time even if your IP address changes
ever so often.
5
Your FSG supports three different DynDNS providers:
- www.dyndns.com
- www.dtdns.com
- www.no-ip.com
Creating a Dynamic DNS account (e.g., no-ip.com) and setting up a host
Note: You will need to register with a Dynamic DNS provider such as www.no-ip.com.
Once you have registered at one of the providers, go to step 1.4.

5.7 Setting up Virtual Private Networks (VPNs)
GB
A Virtual Private Network (VPN) is a computer network that uses a public network such
as the Internet to transfer private data. VPN users can exchange data just like in an
internal LAN. VPN are often used by companies as a way of providing access to the
company network to staff when they are out of the office. The process involves the FSG
establishing a VPN connection to the company's VPN gateway. Using this connection,
the employee is then able to perform his duties as if he/she were working directly in the
company's local area network.
5
Open Connections -> VPN -> ADD Connection in the main menu.
Status
You can enable or disable the VPN connection at any time here.
Name
Please enter any name of your choosing for the connection here.
Remote Host IP
In this field, please type in the IP address of the VPN routers that you wish to connect to
(you need to have an account on this router).
Remote Network
Enter the IP address and the network mask that you want to access. Example: 192.168.1.0/
24. The '0' at the end of the IP address signifies that you can reach any PC in the network
under the IP addresses 192.168.1.1 – 192.168.1.254. /24 indicates that this is a network
mask 255.255.255.0. If the network you are attempting to access contains several
subnets with the net mask 255.255.252.0, please enter /22 in place of /24.
ESP Encryption
This is where you set the encryption protocols. You can keep the default settings,
although they have to be supported by the remote machine.
ESP Encryption 3Des
Triple DES (3DES) is an advanced version of the Data Encryption Standard (DES). The old
DES only used key lengths of up to 56 bits. 3DES on the other hand uses three encryption
cycles and two or three keys. By using three keys, an actual key length of 112 bits is
provided.
MD5
MD5 sums are used by PGP and other programs to check the integrity of files. This
involves comparing the file's current MD5 sum with an accepted sum from earlier. This
allows the system to determine whether the file has been changed or is corrupt.

SHA1
GB
Secure Hash Algorithm (SHA) is the term used to describe a group of standardized
cryptographic hash functions.
5
Working together with the National Security Agency, the National Institute of Standards
and Technology (NIST) developed a secure hash function for signing as part of the Digital
Signature Algorithms (DSA) for the Digital Signature Standard (DSS). It was released in
1994. The name given to it was the Secure Hash Standard (SHS). It specifies the Secure
Hash Algorithm (SHA), with a hash value of 160 bits for messages up to 264 bits in size.
The algorithm shares a similar structure with MD4, designed by Ronald L. Rivest. There
are two versions of the Secure Hash Algorithm: SHA0 and SHA1. They differ in the
number of cycles passed through when generating the hash value.
Pre-Shared Key
Similar to a password. Has to be the same on both VPN routers (FSG and remote VPN
router).
Operation
1. Establish connection - Allows you to establish a connection with another VPN router.
2. Listen Only - Allows you to accept a connection from another router.
Alive Ping IP
You can enter the router's IP address used in establishing a connection in this field. This
involves sending a ping at set intervals to ensure that connection is not cut when no
activity is registered over a long period of time.

5.8 Setting up an FSG Mail Server
GB
An e-mail server, or simply mail server, handles e-mails. It is responsible for receiving,
sending, saving or forwarding e-mails.
5
Note: In the name of spam protection, some freemail providers refuse to
accept e-mails received from dynamic DNS hostnames. Please keep this in
mind when sending e-mails!
Configuring the FSG
The FSG mail server supports POP3 (Post Office Protocol Version 3) and IMAP (Internet
Message Access Protocol) for retrieving and SMTP (Simple Mail Transfer Protocol) for
sending e-mails.
POP3
Communications protocol for retrieving e-mails using an
e-mail client. POP3 allows the user to retrieve and delete
e-mails on the server. A permanent connection to the
POP3 mail server is not required. The fetched e-mails are
stored locally and available offline.
IMAP
The IMAP protocol allows the user to access and manage
e-mails directly on the server using an e-mail client. Unlike the POP3 protocol, the e-mails generally remain on
the server and are only transferred to the client as required. In other words, you need an Internet connection
to read the e-mails. IMAP provides detailed access control
to mailboxes as POP3.
Note: Many freemail providers only support POP3!
SMTP
The SMTP protocol is used to exchange e-mails within
computer networks. SMTP is mostly used to send and
forward e-mails.
Set up a Dynamic client under Services -> Dynamic DNS if you have not already done so.
Your e-mail address corresponds to the hostname that you set earlier, e.g.,
xxx@yourhost.no-ip.org (xxx is a user that you previously added on the FSG; yourhost.noip is the hostname that you selected at the Dynamic DNS provider).
100
Setting up an FSG Mail Server
GB
5
Open Services -> Mail Server and start the mail server by enabling 'Run Mail Server'. Click
'Apply' to start the mail server. The mail server is now ready for use in the internal
network.
To receive e-mails from the outside (Internet), you have to enabled 'Open IMAP and
POP3 Server for the outside'. You may now change the preset default ports. This is
however generally not required. To send e-mails to accounts outside of your network,
you need to enable 'Open SMTP Server for the outside'. You generally do not have to
change the default port (25).
Configuring an e-mail client in Outlook Express
You require an e-mail client to retrieve and read e-mails. Using the e-mail client Outlook
Express, already built-in to the Windows operating system, we will demonstrate which
changes you have to make to the configuration settings. Start Outlook Express. If you
have not already set up an e-mail account, the Configuration wizard will open:

Port Forwarding
5.10 Port Forwarding
GB
Port forwarding allows you to forward ports from clients on the local network to any
port(s) on the FSG that you select. This makes it possible to access services of the local
area network from other networks such as the Internet. Services on certain clients can
thus act as servers as they can now be reached via preset ports that no one else is using.
5
Example using the remote tool VNC
Click 'Services' -> Port Forwarding on the overview. To add a new forwarding, click 'New'.
You may choose any name for the port sharing. You can either share individual ports
(separated by a comma) (see example) or set an entire range of ports by inserting a ':'
between each of them. You can set the protocol in the drop-down menu 'Protocol' and
the client IP address of the port(s) in your local area network under 'IP address. VNC
requires ports 5800 and 5900. Enter these two ports as seen in the illustration below.
Select the TCP protocol and enter the IP address of the computer where the ports are
forwarded. Then press 'Apply'.

Accessing the Internet
GB
If you do not have an Internet account, but still need to access the Internet, you have to
sign an agreement for a Single User Internet Access account with an Internet service
provider. You may use either DSL or cable DSL. You will require a separate modem based
on the type of Internet account you have. These modems are used to access the internet
and are usually provider by your ISP. You can then connect the WAN port on the FSG
directly to a modem. To install the FSG, you need certain information from your ISP.
Please make sure you have this information available to you. This user's manual provides
detailed instructions on how to configure an Internet account on the FSG.
Information on the Internet configuration
Your ISP will supply you with details on TCP/IP configuration (such as IP address, subnet
mask and standard Gateway) for a Single User Internet Account as well as information on
VPI and VCI multiplexing. Your ISP will provide you with other login data such as the
username and password should you require a PPoE or PPPoA protocol. In most accounts,
the lion's share of configuration data is obtained dynamically when the computer is
booted the first time while connecting to the ISP. You therefore do not need to know this
dynamic data.
FSG acts as a single computer in order to enable multiple computers to use the Internet
connection at the same time, your . At this stage, you need to configure it by adding the
TCP/IP data typically required by each of the computers. If WAN port on the FSG is
connected to the modem, the FSG is recognized by the ISP as one single computer. The
gateway allows the computers in the local area network to access the Internet through
the broadband modem using a Single User Account. The method used to access the FSG
is referred to as Network Address Translation (NAT), or IP masquerading.
Login protocols
Some ISPs require a special login protocol, where you are required to enter a login name
and password to access the Internet. If you already log on to your Internet account using
a program such as WinPOET or EnterNet, your account will use PPP via the Ethernet
(PPPoE). When configuring your FSG, you have to enter your login name and password
in the configuration window. Once you have configured your network and FSG, the FSG
automatically logs in for you (where required) and you therefore no longer need to sign
in from your computer. You do not need to uninstall the login program.
118
Appendix
Account data
GB
If the values are not obtained dynamically from the ISP, you should provide your ISP
with the following basic information on your account:
1. An IP address and subnet mask
2. A gateway IP address (the address of the ISP router)
3. One or more Domain Name Server (DNS) IP addresses
4. Host name and domain suffix
The full server name for your account could look something like this: mail.xxx.yyy.com.
(In this example, the domain suffix is xxx.yyy.com.= If any of this information is obtained
from your ISP dynamically, your gateway receives it automatically. If a service technician
from the ISP configured your computer while installing the broadband modem or if you
have configured it following the instructions provided by your ISP, you will need to copy
the configuration data from the 'Properties' window of the Network TCP/IP on your
computer (or the TCP/IP System Preferences on your Macintosh) before reconfiguring
your computer for use with the FSG. This process is described below.
Locating the ISP configuration data (Windows)
If your computer was connected directly to the modem for accessing the Internet, you
may have to obtain the configuration data from your computer for use in configuring the
FSG. If your ISP has supplied this information in print-out form or if it obtains the
configuration data dynamically, you will not require this information. To obtain the
information needed to configure the FSG for Internet access:
1. Click the 'Start' button on the Windows taskbar, go to 'Settings' and then click
'Control Panel'.
2. Double-click the Network icon. The 'Network' form appears on the screen with a list
of installed components.
3. Select 'TCP/IP and then click 'Properties'. The 'TCP/IP' dialog window opens.
4. Open the 'IP Address' tab. If both an IP address and subnet mask are displayed, write
this information down on a piece of paper. Now click 'Obtain an IP address automatically'. If no address is provided, your account will use an IP address obtained
dynamically and you will not require any additional information. Close the window
and continue with the installation of your computer and FSG.
119
Freecom Storage Gateway (FSG)
5. Open the 'Gateway' tab. If an IP address is shown under 'Installed Gateways', write
this down. This is the IP's gateway address. Select an address and click 'Remove' to
delete the gateway address.
GB
6. Open the 'DNS Configuration' tab. If several DNS server addresses are displayed,
write these down. If any information is shown in 'Host' or 'Domain' information fields,
you should also jot this down. Click 'Disable DNS'.
7. Click 'OK' to save your settings and close the 'TCP/IP Properties' window. You now
return back to the 'Network' window.
8. Click 'OK'.
Obtaining the ISP configuration data (Macintosh)
If your computer was connected directly to the modem in order to access the Internet,
you may have to get the configuration data from your computer for use in configuring
the FSG. If your ISP has supplied this information in print-out form or if it obtains the
configuration data dynamically, you will not require this information. To obtain the
information needed to configure the Gateway to access the Internet:
1. Open Apple's 'System Preferences' and hit 'TCP/IP'. System Preferences - 'TCP/IP'
opens and displays a list of configuration settings. If 'Configure' is set to 'Use a DHCP
server', your account uses an IP addressed obtained dynamically and you do not
require any additional information. Please close the window and proceed with the
installation of your computer and FSG.
2. If both an IP address and a subnet mask are displayed, write this information down
on a piece of paper.
3. If an IP address is shown under 'Router Address', write this down. This is the IP's
gateway address.
4. If several name server addresses are displayed, write these down. These are your ISP's
DNS addresses.
5. If any information is displayed in the 'Domain Search' information field, you should
also jot this down.
6. Change settings under 'Configure' to 'Use a DHCP server'.
7. Close TCP/IP-System Preferences.
Restart the network.
Once your computer is configured to work with the FSG, you need to reset the network
so that the devices can properly communicate with each other.
1. Turn off the FSG if it is on. Turn it back on and wait until it has rebooted. (This may take
up to 30 seconds.)
2. Restart all computers attached to the FSG.
Ready to configure
120
Once all computers are set to TCP/IP network mode and connected to the local area
network of your FSG, you can access the FSG and configure it.
Appendix
Appendix C: Networks and Routing Basics
GB
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
255, such as "192.168.0.12".
121
Freecom Storage Gateway (FSG)
This serves the same basic function as a street address. It helps you find out where you
currently are, while also providing other information. The IP address consists of four
numbers between 0 and 255 (e.g., 192.168.0.12).
GB
Domain Name Server
The computer address is difficult to read, which is why a second system is used in the
Internet by the name of DNS (Domain Name Server). This translates human-readable
names such as www.sharemydisk.com into computer readable names like 82.161.11.206.
Each Internet user must have an IP address. You do not need the human-readable name,
but it is quite useful if you want other users to find you. A few examples of this include:
if you operate a web server or if you want to show your friends images stored on your
computer. Many large companies such as ISPs maintain their own DNS server and let
their customers use the server to search for addresses.
Internet address classes
The Internet Assigned Numbers Authority (IANA) allocates certain blocks of addresses to
organizations. Individual users or small organizations can obtain their addresses either
from the IANA or from an Internet service provider (ISP). You can visit the IANA homepage
at www.iana.org. The IANA issues different class of IP addresses. There are five standard
classes of IP addresses. They are:
Class A
Class A addresses can have up to 16,777,214 hosts on a single network. They use an eightbit 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 16bit 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 may have up to 254 hosts in one network. Class C addresses use 24 bits
for network addresses and eight bits for nodes. They range from 192.0.1x to 223.255.254.x.
122
Appendix
Class D
GB
Class D addresses are used for multicasts, in other word messages sent to multiple hosts.
Class D addresses range from 224.0.0.0 to 239.255.255.255.
Class E
Class E addresses are for experimental purposes. For each unique value in the network
portion of the address, the range base address (the host address contains only zeroes)
is known as the network address and is not usually assigned to a host. The top address
of the range (host address contains only ones) is unassigned. It is instead used as the
broadcast address for sending a data packet to all hosts with the same network address
simultaneously.
Netmask
The partition scheme that separates the different address classes is used to identify a
netmask attached to the IP address. A netmask is a 32-bit quantity that, in logical
combination (using an AND operator) with an IP address, forms the network address. The
netmasks for Class A, B and C are for instance 255.0.0.0, 255.255.0.0 and 255.255.255.0.
The address 192.168.170.237 is a Class C IP address; its network portion is 192.168.170.
Combining it with the Class C netmask using an AND operator as shown in this example
leaves only the network portion of the address:
11000000 10101000 10101010 11101101 (192.168.170.237)
combined with:
11111111 11111111 11111111 00000000 (255.255.255.0)
resulting in:
11000000 10101000 10101010 00000000 (192.168.170.0)
An alternative to dotted decimal representation is to express the netmask as the
quantity of ones from left to right. This number is added to the IP address after a slash (/
) as '/n'. In this example, the address 192.168.170.237/24 could be written. This indicates
that the netmask is 24 ones followed by eight zeroes.
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.
123
Freecom Storage Gateway (FSG)
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.
GB
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:
124
•
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:
GB
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 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. 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 Storage Gateway (FSG)
DHCP
GB
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 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 firewall-like 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.
126
Appendix
Network Address Translation
GB
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
GB
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, 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.
