The parameters passed to the component's RequestForwarding method determine which mode the component will operate in. The component also has 'Event Based' mode, where the incoming data is made available through events, and the way this data is used is up to the programmer. This is indicated in the above diagram by the exchange of data between SSHReverseTunnel and the target Server. In 'Local Forwarding' mode, the component will automatically forward data it receives from Local Forwarding Mode versus Event Based OperationĪfter establishing the tunnel, the SSHReverseTunnel component can act in one of two modes. Thus the client is able to communicate with the protected server simply by connecting to the public SSH Host on the port specified by SSHReverseTunnel. The response data goes back through the SSH tunnel to the SSH Host, where it is visible to the client. To the target Server and receives the response. SSHReverseTunnel establishes an SSH tunnel with the public SSH host onĪny open port (represented here by XXXX), and requests that traffic on this port is forwarded to SSHReverseTunnel. In the above diagram, SSHReverseTunnel is connected to the target server within a protected network. The following diagram illustrates a typical SSHReverseTunnel scenario: The SSHReverseTunnel component can be used to create a 'middleman' which establishes this tunnel and requests this forwarding.Ĭonceptually, SSHReverseTunnel opens a door from the inside and invites traffic through that door.
This traffic is forwarded through an established tunnel to a 'middleman' inside the firewall-protected network,Īnd this 'middleman' then forwards the data along to the target endpoint within the network. The client instead connects to a publicly accessible SSH host.
Rather than connecting directly to the target network, SSH Reverse Tunnels use traffic-forwarding to bypass network restrictions.

This guide will cover the basics of establishing and using a reverse tunnel with the SSHReverseTunnel component.īefore continuing, it is recommended to download IPWorks SSH in order to follow along with this tutorial. For example, a server behind a firewall can be accessed throughĪn SSH Reverse Tunnel without needing to authenticate through the firewall. SSH Reverse Tunnels provide a way to establish connections to network resources that would not typically be available.
