The next day after installing SSH, you observeĬomment on the above example.
Now, the data is encrypted using the SSH protocol, and is virtually Plaintext and could be captured by anyone parking on the street below. Previously, the data that was being radioed between the two buildings was sent in Server, which decrypts it and forwards it to your application server.ĭata sent by the server application is similarly encrypted by the SSH The SSH client forwards the encrypted data to the SSH Rather, it connects to the SSH client, which encrypts all data before Now, your application client doesn't connect to the server directly anymore. That connection to host 127.0.0.1 (relative to the server), port 123. With the following client-to-server port forwarding rule: for eachĬonnection that comes on interface 127.0.0.1 and port 999, forward thatĬonnection to the SSH server, and request the SSH server to forward

Machine in Building #2 that runs the server for your legacyĪpplication, you install an SSH server. Workstation 10.1.1.7 is shown), you install an SSH client. On each of the client workstations in Building #1 (in the above example, The two buildings, he becomes worried that the van parked outside mightīe collecting the company's confidential information. Realizes that sensitive data is being transmitted unencrypted between The street between the two buildings for several days. Your company notices that an unmarked black van has remained parked on That uses an unencrypted TCP/IP session to communicate sensitive data Workstations in Building #1 are running a legacy client application Wirelessly through an antenna on the roof of each building. Spaces on each side, and the subnets in the two buildings are linked The two buildings are separated by a busy street with parking Inīuilding #2, there are multiple servers residing in the subnetġ0.2.2.*. There are numerous workstations residing in the subnet 10.1.1.*. Suppose you are the networkĪdministrator in a company that has two buildings. Port forwarding can be used to establish a form of a virtualįorwarding works, let us use an example. TCP/IP connection that would otherwise be insecure is tunneled throughĪ secure SSH link, thus protecting the tunneled connection from networkĪttacks. Port forwarding, or TCP/IP connection tunneling, is a process whereby a
