In this post, we are gonna explain how to establish tunnel between local machine to your server. The following are the few use cases.

  • When any application/domain is restricted particularly to the network.
  • When you want to open the application/domain which is in private network.
  • If you are looking to book IRCTC ticket :P. There is a restriction in irctc network where you will be allowed to book only 2 tatkal ticket from particular IP address

Prerequisites:

  • SSH access to the machine
  • Putty client or terminal

Implementation:

Open your putty and configure the following settings.

1.Under Session, add the following details

Hostname(or IP address):<Your Server IP address>

Port: <SSH port number> Default it will be 22

Connection Type:SSH

putty_config

 

 

 

 

 

 

 

 

 

 

 

2. On the putty, move to SSH > Tunnels and configure the tunnel.

Source port:1990

Destination: Select Dynamic

Click on Add

putty_tunnel

 

 

 

 

 

 

 

 

 

 

 

 

3. Click on Open. Enter the username and password. Thats it. A tunnel is established. Now, we are gonna show you how to configure firefox to use the tunnel.
