I believe unotelly is not a vpn but a dns service. Ryan already posted about this service here: http://www.vpnforums.com/index.php?topic=103.0

Public WiFi hotspots are great, but did you know that you are the prime target for hackers in public WiFi networks if you are not equipped with the right safety tools? With the cyber crime rates on the rise, it is better to take the extra precaution to keep your personal information safe from predators, who are looking to intercept your connection to steal your identity. Don't let this happen to you.
I've had my share of identity theft and I can tell you it's the most annoying thing you'll have to go through to clean that up. I knew for a fact that I didn't sign up for another Netflix account when I already had one and that I was right here in San Francisco when my credit card bill showed that I just had lunch in Texas. Hey, if I could be in two places at once or travel through a time capsule, that would be so magical, but we all know that those things are impossible. And that is why I bring you this deal today, just in time for you to finish your holiday shopping.
Rated 4.5 stars by CNET, Hotspot Shield Elite VPN (virtual private network) is a must have utility if you are connecting to public WiFi hotspots. It provides you with a cloud-based protection against malicious, infected and phishing websites, so you can shop and browse worry-free. In addition, if you are traveling to countries, where certain websites or content are blocked or censored, you can now access them without a problem.

I also cannot find the reply button.

The workaround that I do is this.

1. Go back to your inbox and right click the message you want to reply.
2. From the context menu that popped up select "reply to sender".
3. And there you go, you can now tyoe your message and reply to your email.

Or just press letter "R"

Changing Your DNS Settings for Tunlr.net on Windows

 Press the Win + R keyboard combination, then type ncpa.cpl into the run box and hit enter.



Then right-click on your current network adapter and choose properties from the context menu.


When the properties dialog opens, scroll down and choose Internet Protocol Version 4 (TCP/IPv4), then click the properties button.


Then change your DNS Settings to the following IP’s:
 

• Preferred DNS: 149.154.158.186
• Alternate DNS: 199.167.30.144

Click OK, and then browse away.



When you are done browsing the restricted sites, you should change your DNS settings back to what they were before you changed them.

Recently, a new free service called Tunlr has emerged that allows users to access services blocked outside the United States. But Tunlr does not provide VPN service. It is a DNS unblocking service that uses a combination of a DNS server and a collection of proxies in various countries to go around the geographical block. The user simply change their DNS servers to those provided by Tunlr. After doing this, they are able to bypass the block and access Hulu, Netflix, Pandora and any of the supported services.
Unlike VPN, where the content is routed through the VPN servers, with Tunlr users are able to stream directly from the blocked service with no intermediary servers in between, which means you can get faster download/streaming speeds that a VPN.



What's great about this service is it is totally FREE.
Tunlr can unblock the following services:
 

• US video streaming services: Netflix, Hulu, CBS, ABC, MTV, theWB, CW TV, Crackle, NBC, Fox, TV.com, PBS, Vevo, History, Lifetime TV,
• US audio streaming services: Pandora, Last.fm, Turntable.fm, Mog.com, iHeartRadio,
• Non-US services: BBC iPlayer (UK), Channel4 4oD (UK), iTV Player (UK), and Zattoo (Germany).

  How Does Tunlr Work?  Tunlr uses two main components - a DNS server and a collection of proxies located in different countries. When your computer sends a DNS query for a blocked website, for example, hulu.com, instead Hulu’s real IP address, the Tunlr DNS server returns the IP addresses of a proxy server operated by Tunlr in the US.
When your connection is received by Tunlr’s proxy in the correct country, it is forwarded to the service provider e.g. Hulu. For Hulu, you appear to be in the correct country because it sees the IP address of the proxy server located in the US.
Once the IP address check is passed, and your connection established, Tunlr re-introduces your true IP address into the data stream so that the video content is streamed directly to your computer and not through Tunlr’s proxy server.
In order not to overwhelm their DNS servers with request, Tunlr strongly recommends that you switch to their DNS servers only when required to access the blocked services.

To use a VPN, you will need admin rights. OpenVPN needs admin rights to install the TAP Driver and to setup the network routes. AFAIK there is no other workaround for that.

The Absolute Minimum Server Setup
What follows are the absolute minimum instructions that you need to get a basic PPTP VPN server running under Ubuntu. Clients will then be able to VPN into the server and route  their internet traffic so that it goes through the server to the internet. As always, consult the full documentation to understand what everything is doing.
First, install the required software:

sudo apt-get install pptpd 

Second, enable ip_forward in the kernel for IPv4 by uncommenting the associated line in /etc/sysctl.conf:

sudo sed -i -r 's/^\s*#(net\.ipv4\.ip_forward=1.*)/\1/' /etc/sysctl.conf # Reload the config file to have the change take effect immediately. sudo -i sysctl -p 

Third, enable NAT (if it isn't enabled already) so that users on the private VPN network can have their packets routed out to the internet:

OUTIF=`/sbin/ip route show to exact 0/0 | sed -r 's/.*dev\s+(\S+).*/\1/'` sudo -i iptables --table nat --append POSTROUTING --out-interface $OUTIF --jump MASQUERADE # Enable NAT on boot from the rc.local script. CMD="iptables --table nat --append POSTROUTING --out-interface $OUTIF --jump MASQUERADE" sudo sed -i "\$i$CMD\n" /etc/rc.local 

Note: This guide assumes you have no firewall configured on the server. If you have a firewall on the server, such as UFW, consult the relevant documentation instead.
Fourth, for each VPN user, create an account in the file /etc/ppp/chap-secrets. Replace $USER with the actual username you want to use for that VPN user.

KEY=`head -c 20 /dev/urandom | sha1sum | nawk '{print $1}'` echo "$USER pptpd $KEY *" | sudo tee -a /etc/ppp/chap-secrets 

Finally, you are ready to...
Configure the Client
In the Network Manager applet, select VPN Connections → Configure VPN, then click Add. On the next screen select PPTP for the VPN type, then click Create.

In this window, enter your server's hostname or IP along with the username and key that you added to the /etc/ppp/chap-secrets file on the server.
Now click Advanced.

In this window, enable "Use Point-to-Point encryption (MPPE)" and select 128-bit security. Disable the use of MSCHAP authentication (leave MSCHAPv2 enabled).
Finally, click Ok and then Save to close out the previous window.
You can now test the VPN connection by going to the Network Manager applet → VPN Connections and selecting the connection that you just created. Make sure you get a message saying that the VPN connection was successful, then browse to an IP checking website to verify that your IP now shows up as the server's IP.
If you get a message saying that the VPN connection to the server failed: first verify that you correctly entered the client settings; second, check that the client has network connectivity to TCP port 1723 on the server; finally, check the log file /var/log/messages on the server for further clues. If your VPN connection succeeds, but you subsequently are unable to browse to any websites from the client, consult this incredibly helpful diagnostic guide on the pptpd website.
Notes
If the local network you are connected to is using the 192.168.0.0/24 and 192.168.1.0/24 subnets, you are going to run into issues because that is what the PPTP server uses by default. You will have to configure PPTP to use different subnets in pptpd.conf.
There are numerous other configuration changes you may want to make. For example, all your domain name lookups will still be queried using your local DNS server instead of going through the PPTP server. Take the time to read over the full documentation to find out how to change this setting and many others.
 

It's used to allow secure remote access to a network. The second paragraph from the Wikipedia article sums it up nicely:

    It encapsulates data transfers between two or more networked devices which are not on the same private network so as to keep the transferred data private from other devices on one or more intervening local or wide area networks.

It effectively makes the remote machine part of host network for access to resources and other machines on that network. So you can use the company e-mail, intranet and printers for example.

Today it is normally being used to bypass blocked websites by users with a censored and filtered internet connection.
