With so many people constantly on the move, the temptation to use
an open Wi-Fi network like those found in coffee shops and fast food
restaurants increases daily. The problem with open networks is that
although the internet connection is free, your data becomes vulnerable
to hackers or people with the knowledge to steal your information right
out of the air.
Simple things like checking your email, logging
onto your banks website, or any other secure search on an open wireless
network, sends your username and password over the air just long enough
for someone who knows what they are doing, to steal your information and
your identity. This is where VPN's or Virtual Private Networks have
grown in popularity over the years. They provide the user with a secure
way of surfing the web.
Until now, you only had two choices when
it came to secure web searches, VPN's or Dedicated Security Appliance.
VPN's are easy to install and use. If you know how to download an app
and put in a username and password, you are pretty much set. The
downside to using VPN's is the monthly service fee if you are using the
paid version. The free versions while cost effective come with
advertising for their service, which can get disruptive. VPN's also do
not help you to get back to your ISP, which is another downside.
Dedicated Security Appliance's requires and intermediate knowledge of
computers in order to set up that method. Once set up though, the usage
is relatively simple. This solution uses your very own firewall to help
you achieve secure web browsing. The downside is that you would still be
using your own ISP network, and it can be expensive to set up.
Another
option is to build your very own VPN with DD-WRT to achieve secure web
browsing. There are about four steps to this process with an important
warning. Do not use your primary router for this job, as you may need to
use the internet to troubleshoot problems.
1. Getting DDT-WRT
Even though you can look up online how to flash a router with
DD-WRT, your router still needs to have a compatible version of DD-WRT
with the VPN tab under services. If the VPN tab is not there, update the
instillation. Then you will need a good power source. If your router is
struggling power wise under its regular load, this will put it past the
breaking point, so make sure you have a big enough power source.
2. Write down the installation process
This is extremely important and you will need four things:
a. The username and password of the router you will be using.
b. The external IP address of the router (192.168.1.300) for example.
c. The internal IP address of the router (192.168.300.1) for example.
d. Finally, you will need the internal DHCP range of the router.
b. The external IP address of the router (192.168.1.300) for example.
c. The internal IP address of the router (192.168.300.1) for example.
d. Finally, you will need the internal DHCP range of the router.
3. Enabling the Virtual Private Network Servers
Even though a security flaw has caused the DD-WRT VPN servers to
depreciate, and that flaw is hard to exploit, it is still a good starter
VPN server. As time goes, you may want to move to an open VPN. The
first step is to login and go to the "Services" tab. Next, click the
"VPN" sub-tab where there will be two boxes, the "PPTP Server" and the
PPTP Client. Click the "PPTP Server". Enter the external IP address of
your router in the "Server IP" box. Then, you want to enter a range of
IP's that the connecting computer will be using into the "clients IP"
box (For example 192.168.300.310-320- etc.). Also, make sure to use the
internal range of the router. Enter the usernames and passwords into the
CHAP-Secrets section, putting each entry on a new line.
4. Enabling the Client
Each mobile client may be a bit different, but the basic principle
is the same. For Android devices with Android 4.1 or higher, the steps
are as follows.
o Go into configurations
o enter the "more networks" tab
o click "VPN"
o then click the "+" sign to add a VPN
o Name it
o Type in the server address
o Click save then click the connection
o Enter your username and password the click connect and you should be done.
o enter the "more networks" tab
o click "VPN"
o then click the "+" sign to add a VPN
o Name it
o Type in the server address
o Click save then click the connection
o Enter your username and password the click connect and you should be done.
Now that you know how to create your own VPN, surfing the web will now be a safe activity. Enjoy!
