access to www.google.com, then enter this address in the ‘Domain Name’ field.
5. Check ‘Enabled’ in the ‘Status’ field.
6. Click ‘Save’.
7. It is now impossible to reach this domain or website during the specified time
frame.
10.4 Denying Internet access using ‘MAC Address
Filtering’
Apart from the methods to restrict Internet access as explained above, there is
another way to deny Internet access. This method is also the most effective. Access to
the Internet is completely blocked and you do not need to specify a time frame. To

DHCP, Automatic allocation of ip-addresses
For the development of DHCP (Dynamic Host Configuration Protocol), TCP/IP settings
are configured manually on each TCP/IP client (such as your computer for example).
This can be a difficult job if it is a big network or if something has to be changed
regularly in the network. DHCP was developed to avoid always having to set up an IP
address. With DHCP, IP addresses are allocated automatically when necessary and
released when no longer required. A DHCP server has a series (‘pool’) of valid
addresses that it can allocate to the client. When a client starts for example, it will
send a message requesting an IP address. A DHCP server (there can be several in a
network) responds by sending back an IP address and configuration details. The client
will send a confirmation of receipt after which it can operate on the network.
Translating ip-adresses and domain names
IP addresses are far from user-friendly. Domain names are however easier to
remember and use. The process of translating a domain name into an address that is
understandable for a machine (such as your computer) is known as ‘name resolution’.
A ‘Domain Name System’ server carries out the afore-mentioned process. Thanks to
DNS, you use domain names instead of IP addresses when visiting a website or
sending e-mails.
Dynamic DNS or DDNS is a DNS-related option. You can still link your IP address to a
domain name using DDNS if your provider works with dynamic IP addresses
(‘dynamic’ here means that the IP addresses change frequently). After all, the IP
address to which your domain name refers will also change when your provider
changes your IP address. You must register with a Dynamic DNS provider such as
www.dyndns.org and www.no-ip.com in order to use Dynamic DNS.
Using a single ip-address for your entire
network
Network Address Translation (NAT) is an Internet standard with which a local network
can use private IP addresses. Private IP addresses are those used within an own
network. Private IP addresses are neither recognized nor used on the Internet. An IP
address used on the Internet is also called a public IP address.

20 | EMINENT ADVANCED MANUAL
NAT enables you to share a single public IP address with several computers in your
network. NAT ensures the computers in your network can use the Internet without any
problems but users on the Internet will not have access to the computers in your
network. You will understand that NAT also offers a certain level of security partly due
to the fact that private IP addresses are not visible on the Internet.
Fortunately, most routers currently use NAT.
Security for your computer and your network
A firewall can be a software- or a hardware solution placed, as it were, between the
internal network and the outside world. Firewalls generally control incoming and
outgoing data. Firewalls can be adjusted to stop or allow certain information from the
Internet. Firewalls can also be adjusted to stop or allow requests from outside. Rules
or policies are used to adjust firewalls. These state what a firewall must stop or allow
and thus form a sort of filter.
Most routers have various firewall functions. The big advantage of a firewall in a router
(hardware solution) is that an attack from outside is averted before reaching your
network. If you wish to use a software firewall, you could for example, use the firewall
built into Windows XP Service Pack 2. There are better alternatives such as the free
ZoneAlarm and the commercial packages from Norman, Norton, Panda and McAfee.
These commercial packages also offer protection against viruses if required.
Making a computer available for Internet
users in your network
The DMZ or DeMilitarized Zone is the zone between the outside world – the Internet –
and the secure internal network. The computer placed within the DMZ is accessible
via the Internet. This is in contrast to the computers that are outside the DMZ and are
therefore secure. The DMZ is therefore also often used for servers that host websites.
Websites must after all always be accessible via the Internet. A computer is also often
placed within the DMZ if one plays a lot of online games. It is however advisable when
you place a computer in the DMZ to fit a software firewall (such as the free
ZoneAlarm). This is because the firewall opens all ports of the router for a computer
within the DMZ. There is therefore no restriction on data transmission while this is
however desirable in some situations.
Just like the DMZ function, Virtual Server enables you to make a computer, set up for
example, as an FTP- or a web server, accessible from the Internet. You can state
which ports in the firewall must be opened when using a Virtual Server. This is also
the most important difference with the DMZ: when you place a computer in the DMZ,
all ports are opened for the respective computer. If you use Virtual Server, you can
open only the ports important for the respective computer.
