Setup ssh tunnel in putty7/9/2023 You can download putty from internet free. It is not necessary to install it since it is a Portable program, we open Putty and we have the following screen: The program that we are going to use is Putty, it is a Windows program, but in Linux it works perfectly using the WINE utility. Once we have the SSH server running, we proceed to configure the client. This SSH tunnel that we are going to create only encrypts the communications if we configure a Proxy in our browser, the tests have been done with Firefox. This method does not encrypt the services of MSN, Skype, or similar if we have not previously configured in these programs the use of a proxy server. If we want to encrypt absolutely EVERYTHING, including these services, we must follow the How to create OpenVPN. In this tutorial I will explain how to create an SSH tunnel and be able to surf the web in a secure way as if we were in our home. The tutorial that I present is valid for both Windows and Linux, although in Linux there is a command that saves you many unnecessary steps. Browsing The Web Through An SSH Tunnel (Putty / Firefox) If all you need to secure is your web browsing, there is a simple alternative: a SOCKS 5 proxy tunnel. The simple solution is a VPN, but most VPNs requires a client software on your PC, and you may not have administrative rights to install the software. You want to access it with secure way that no one in the middle can watch the traffic. EXE” -l jolly -pw password -4 -L 8888:172.30.10.Sometimes you are in a network which is insecure or with an overly-restrictive firewall, and you want to access a web site. Insert the following line as the target for the link: PuTTY can be used by passing numerous parameters. The SSH option AllowTcpForwarding yes must be enabled on the server, default is yes entered in the server configuration file /etc/ssh/sshd_config.įor the host behind a firewall, it must be accessible via port 22 Static NAT forward. Other ways to use SSH tunnels are available for Synology DS, SAN Memory, Unix/Linux Hosts, or Mac OS X. After that, as here in our example, the login dialog of the SIP-Phone WebGUI begins, which we can now configure. Now you open the web browser and enter the following localhost address. There you log in as a normal user, so the tunnel is established. The well-known terminal console opens with the prompt to log in. The settings are saved above under Session by clicking on Save Permanent.Ĭlicking on Load and Open will establish the connection. The data from the tunnel has now been adopted. The action is completed with a click on Add. After that, the starting point and the end point of the tunnel are entered:ĭestination: 172.30.10.10 PuTTY SSH port forwarding In the lower part of SSH, the tunnel point is selected. Here in our example, on the host 212.117.203.98, our PBX is made with the port forwarding to a SIP phone, and then configured via the web browser, the host can also be an FQDN of a DNS resolvable host. PuTTY can produce more than just terminal sessions, with the option SSH port forwarding can be initialized in simple ways.Īfter PuTTY is started, you enter the IP of the target host under host name, or the server name, which is usually a firewall, a router or a host with a global IP address.
