8. Then launch putty and enter your connection details. This will be the IP address of your Linux server and 80 as your port
9. On the left hand side of the putty configuration window, select tunnels
10. In the source port section, enter any port you like (I used 8080).
11. In the destination section, enter your home PC ip address along with 3389 as your port and click Add
12. Once thats done, click open to establish a SSH connection to your Linux server. Login with the user that you have setup previously.
13. Now your tunnel has been established. You can launch your favourite remote desktop client and connect to your PC using localhost:8080 as shown below:
14. Voila done!
How do you block these bastards?
So you’re a security administrator and you’re looking for a way to block Teamviewer and guys who are using methods such as tunneling or portforwarding? Can you do this on a traditional firewall? The answer is NO. You will need to rely on a device that performs layer 7 inspection. These appliances are called Web Security Gateways. Vendors such as Cisco offers Iron Port or Bluecoat’s secure web gateway can be utilized to perform layer 7 deep packet inspection. They usually come with templates and packaged solutions that will allow you to tackle these tunneling products and ensures that you are only allowing genuine http traffic.
How can you bypass Web Security Gateways?
The answer is you can’t! If a company has deployed this and has properly implemented it, you’re screwed. What you can do however, is get yourself a smartphone with a data plan. Thether off of that, as you don’t have any means of using your company’s internet to get anywhere.
Good luck!
