Virtual Private Network
you need access to your data on a network while you're on the go, you
need a Virtual Private Network (VPN). VPN technology lets a computer
using a public internet connection join a private network by
establishing a secure tunnel between that machine and the network. It's
commonly used in offices where employees need to access the data on
their network from remote locations.
Windows 7 has a preloaded VPN client and it's very easy to set up a VPN in it.
First let's see how to build a VPN.
Setting up a Virtual Private Network
1. Open the Network and Sharing Center.
2. Click "Change Adapter Settings" in the left hand menu
3. Press Alt key to get the menu. From the File menu, select "New Incoming Connection".
You'll now be able to see a list of users you can allow to connect to
your computer. Select the users you'd like to give access to and click
5. Check the "Through the internet" checkbox.
6. Select the TCP/IPv4 protocol
7. Finally, click "Allow access"; you've now set up an incoming VPN connection.
8. Make a note of your IP address as you'll need it to connect to your VPN.
Connecting to a VPN
1. Now that we know how to set up a VPN, here are step-by-step instructions to connect to one.
2. Click the Start button and type VPN in the search bar and then select "Set up a virtual private network (VPN) connection".
3. Enter the IP address or domain name of the server to which you want to connect.
You can choose to set up the connection, but not connect by selecting
"Don't connect now" or leave it blank and click "Next"
5. Enter your username and password and click "Connect".
To connect, click on the Windows network logo on the lower-right part
of your screen; then select "Connect under VPN Connection".
past chapters, we saw how to connect all your devices to one network.
Since all your data is on this network, it's extremely important that
you secure it. An unsecured network can give any hacker access to your
data and passwords.
To get started, you'll need to log in
to your router's administrative console by typing the router's IP
address into your web browser's address bar. Refer to your router's
manual for this address (usually 192.168.1.1)
There are a few simple but effective ways to secure your network.
Enable WPA2 encryption
new WPA2 encryption offers better security than its predecessors - WEP
and WPA. You can choose the type of security when you create your
network. Make sure you enter a strong security key.
is the simplest way to protect your network. Keep changing your
passwords regularly. Although no password is foolproof, you can build a
complex password by using numbers and special characters. You'll have to
manage two passwords - Wi-Fi and router. Most often we forget to change
the router password. The default password is "admin" which is pretty
easy to guess. Make sure both your passwords are strong and do not use
birthdays or pet names as passwords.
Limit your connections
you always use the same number of devices, you should set your router
to allow limited number of connections. Dynamic Host Configuration
Protocol (DHCP) makes it easy for your network to manage how many
devices can connect to your Wi-Fi network at any given time, by limiting
the number of IP addresses your router can assign to devices on your
network. Open your router administrator settings and go to DHCP
settings. Here you can change the number of client leases as per your
requirement. You can keep the number one higher than the devices you
have for guests.
Block WAN requests
can conceal your network from other users by enabling the Block WAN
Requests option. Once this feature is enabled, your router won't respond
to IP requests by remote users, preventing them from gleaning
potentially useful information about your network. Also disable remote
administration privileges through the router administrator so no one can
change your router settings wirelessly.
device that can connect to a network has a unique MAC (Media Access
Control) address. It's composed of six pairs of alphanumeric characters.
Using the MAC address you can allow only specific devices to connect to
your network. To know the MAC address of a Windows PC, open the Command
Prompt. Type ipconfig /all and press Enter to bring up your IP
settings. Here you'll be able to see the details of your network along
with the MAC address under the name of Physical Address.
you're on a Mac, open System Preferences and click "Network". From
there, select Wi-Fi from the list in the left-hand column, click
"Advanced" and look for Airport ID or Wi-Fi ID. If you want to find the
MAC address of a handheld or any other device, check the user manual.
You can also find the MAC address of this device if it's connected to a
network. Your router displays a list of devices connected to your
network along with their MAC address in the router administrator.
