![]() A setup page should appear as soon as you install the extension, or click the icon in the top right of Chrome and click Options.Set SOCKS Host as 127.0.0.1 and the port as 8080 (or whatever you set the tunnel port to on PuTTy).Go to Tools > Options > Advanced > Network > Connection > Settings > Manual proxy configuration.Here are the instructions for Firefox and Chrome: If you need to set it up manually, the three pieces of information you need are: Many apps will have a proxy setup available in the settings, and some may even auto-detect it. This is similar to what we did with the basic SSH proxy from the last tutorial. The last step is to configure your apps to use the proxy over port 8080. Save your new config file into the config folder of your OpenVPN directory. Note the second “remote” line uses localhost instead of the OpenVPN server IP, plus the two lines on the end that configure OpenVPN to use a SOCKS proxy. Open or create your new config file, which should look like this: Find Notepad or another plain text editor and right click it to Run as administrator. If you used the default installation directory, this will be C:/Program Files/OpenVPN/config.Ĭreate a copy of your existing OpenVPN config file from the last tutorial or create a new one. On your local machine, navigate to your OpenVPN client config files. Then click CTRL+O (the letter “o”, not zero) to save the file, then CTRL+X to exit the editor. If you need to change it, you can edit it with this command: The important thing is that the second line is set to TCP, not UDP. This should display the contents of your OpenVPN server configuration file. Navigate to your nf file and check the contents using these commands Remember that on the newer Amazon Linux AMI, the username is “ec2-user”. You can save this as a separate session configuration if you want back on the Session tab of the navigation tree.Ĭlick Open and log into your server. You now have an SSH proxy running through port 8080. If not, type 8080 into “Source port” and check Auto and Dynamic. In the sidebar, navigate to Connection > SSH > Tunnels. Open PuTTy and load up your VPN server configuration. This approach combines the two, which means you should already have everything you need. In our last tutorial, we discussed how to set up a simple SSH proxy, then expanded on that to create a full-on VPN server. If you don’t have all that set up, please refer to our previous tutorial. For demonstration purposes, we’ll be using PuTTy. You must also be able to SSH into your server using either Terminal on a Mac or PuTTy or one of many PuTTY alternatives on a PC. This tutorial assumes you already have a functioning OpenVPN server set up and can connect to it using the OpenVPN GUI or OpenVPN Connect app. SSH tunneling can be used on an Android or iOS mobile device. ![]() Unfortunately, Obfsproxy combined with OpenVPN currently only works on a desktop, so far as we are aware. ![]() Obfsproxy is much more powerful for this reason, but also more complicated to set up and run. ![]() In this case, we recommend you set up Obfsproxy instead, which makes encrypted traffic appear to be normal and un-encrypted. This is the case for services like Netflix, which halt the use of any type of encrypted proxy, OpenVPN, SSH, or otherwise. Second, OpenVPN’s fingerprint can no longer be detected when tunneled through SSH, but some firewalls block SSH traffic as well. First is a performance hit due to the double encryption. OpenVPN over SSH does have a couple downsides. Each of these methods should bypass DPI and SPI firewalls put in place either by corporations or censorship-heavy governments like China’s. SSH tunneling wraps your already encrypted connection in another layer of encryption so the firewall can’t make the distinction. In this tutorial, we’ll discuss the lattermost. There are three options to get around this: an obfuscation proxy, SSL tunneling, and SSH tunneling. That means they can detect OpenVPN traffic and flag it so the admin can block the server. So what do you do?īasic firewalls block connections based on the port used and the destination IP address, but more advanced firewalls use deep packet inspection (DPI) and/or stateful packet inspection (SPI) to distinguish between different types of encryption algorithms and VPN protocols. It seems your office, ISP, or government is actively blocking OpenVPN servers. It work great again for another couple days, then gets blocked. Maybe you rebooted the instance and got a new IP address. So you followed our tutorial on how to set up your own VPN server using OpenVPN and an Amazon EC2 server, and it was working great.
