A scanned FIPS 140-2 Validation Certificate document is available for download on the NIST web page. It can benefit from the FIPS 140-2 validation of the OpenSSL FIPS Object Module, as long as the building process meets its Security Policy. Stunnel uses the OpenSSL library for cryptography, so it supports whatever cryptographic algorithms are compiled into the library. Its architecture is optimized for security, portability, and scalability (including load-balancing), making it suitable for large deployments. The route your traffic goes looks like this: Client -> OpenVPN-Client -> Stunnel4-Client -> Stunnel4-Server -> OpenVPN-Server -> Internet/LAN.Functionality to existing clients and servers without any changes in the programs’ code. Now everything is set up, you should be able to connect to your OpenVPN server over an HTTPS-tunnel using stunnel4. This is the easiest part, you have to change just one line in your /etc/openvpn/nf file to actually use stunnel

To configure your client to connect to your server, add the following lines to your /etc/stunnel/nf fileĬonnect = :443 Configure your OpenVPN client On the other hand, SSH tunnel works on the. Such that, when a computer is connected to the internet, all traffic passes through the VPN tunnel. This explains why a VPN app must install a virtual network adapter after installation. It operates on layer four, also known as the transport layer. Start stunnel via sudo service stunnel4 start - now your server is ready for incoming connections. VPN operates on a lower level as compared to SSH. #your client connects to port 443 and your OpenVPN server is listening on port 1194 The /etc/stunnel/nf file should contain these lines: To be able to actually start stunnel, you have to enable it by setting the option in /etc/default/stunnel4 to:ĮNABLED = 1 Configuring your stunnel server This creates a new user/group called stunnel4 so the stunnel-instance is able to run in its own user context. The easiest way is to just install it via apt-get But if you want to tunnel your vpn-connection through an SSL-tunnel to make it look like you are connecting to an HTTPS-Server, follow these instructions - this might help if the described setup with obfsproxy does not work, because blocking all HTTPS-traffic would cripple the internet quite severely.

How to install your OpenVPN server and set everything up to connect with a client I already explained. Some internet service providers perform DPI (Deep Packet Inspection) on the traffic, which allows them to identify and block VPN connections.
