Summary of SSH Tunneling, Reverse Tunneling, and SSH Proxy

Very recently we have finished a series on SSH Tunneling, Reverse Tunneling, and SSH Proxy configuration. You can read the full-length summary here, however in this news post, we will provide a brief summary.

In those blog posts, we have described the basics of our ssh tunneling infrastructure. The system now serves as our gateway to access devices from work, for example, and also provide a convenient web proxy as a replacement of our VPN. In the following sections, we recapped through some of our use cases:

  1. Use of SSH Proxy as a replacement of VPN
  2. Connect to home computer via ssh
  3. Forward services from home to office
  4. Access resources on local LAN from a shared remote

Use of SSH Proxy as a replacement of VPN

Our browser is google-chrome, and we want it to connect to our cloud server via a proxy. Therefore we can configure google-chrome to connect to the internet via the configured proxy. The configuration should make google-chrome dependent on the proxy to be present, otherwise it should not be able to connect to the internet.

Connect to home computer via ssh

The problem with a normal home network is that it is hidden behind a NAT. Moreover setting up port forwarding is not exactly trivial for end-user. Therefore, since we have a readily accessible remote server, we can leverage it for our purpose.

Forward services from home to office

We have some services that we would like to be made available at office for convenience reason. For security purposes we have to use ssh tunnels instead of exposing the port from our home network’s port forwarding. It takes one cloud device we control that we utilized as a bridge between our home computer and office computer.

Access resources on local LAN from a shared remote

We have certain resources accessible only from home LAN, and we want to connect to them from anywhere. Given that we have a high availability cloud server, we can use it as a reverse proxy to access specific services we wanted to access. A custom configuration is required, and will be outlined in the article below.
