Intune Device Configuration policies support VPN settings with L2TP and a certificate (but not with a Pre-Shared Key). If I could work out how to use an authentication certificate, then that would be the better option.

Engines []. Some third parties provide OpenSSL compatible engines. As for the binaries above the following disclaimer applies: Important Disclaimer: The listing of these third party products does not imply any endorsement by the OpenSSL project, and these organizations are not affiliated in any way with OpenSSL other than by the reference to their independent web sites here. The commands below demonstrate examples of how to create a .pfx/.p12 file in the command line using OpenSSL: PEM (.pem, .crt, .cer) to PFX openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile more.crt Breaking down the command: openssl – the command for executing OpenSSL When integrated with OpenSSL, OpenVPN encrypts all VPN traffic providing a secure connection between machines. An OpenVPN connection consists of two flow channels between the server and clients: the Control Channel and the Data Channel . In the top menu, go to VPN -> OpenVPN. Set the checkbox Enabled for VPN connection you just created, and click Save & Apply. After the settings are saved, click Start button next to the VPN connection. Wait a few seconds for connection to establish. You can check here if you have successfully connected. Implement custom HTTP header (TCP) Config Example : http-proxy-option CUSTOM-HEADER Host bam.entelpcs.cl http-proxy 10.99.0.10 8080; Latest OpenSSL 1.0.1h Apr 04, 2018 · The OpenSSL VPN traffic would then be practically indistinguishable from standard HTTPS traffic that occurs when you connect to a secure website. This makes it difficult to block completely. It’s very configurable, and will be most secure if it’s set to use AES encryption instead of the weaker Blowfish encryption.

openssl is you can say just a encrytion/authentication functions library. A clear difference could be understood wh a little example. Suppose you want to secure traffic between two machines so you create secure encrypted packet , send it to other machine there it needs to be decrypted based on security associations.All this is part of IPSEC

OpenSSL is a software library for applications that secure communications over computer networks against eavesdropping or need to identify the party at the other end. It is widely used by Internet servers, including the majority of HTTPS websites.

Jun 26, 2020 · A pre-shared key (also called a shared secret or PSK) is used to authenticate the Cloud VPN tunnel to your peer VPN gateway. As a security best practice, it's recommended that you generate a strong 32-character shared secret.

It uses the OpenSSL encryption library extensively, as well as the TLS protocol, and contains many security and control features. OpenVPN has been ported and embedded to several systems. For example, DD-WRT has the OpenVPN server function. SoftEther VPN, a multi-protocol VPN server, also has an implementation of OpenVPN protocol. OpenSSL is a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It is also a general-purpose cryptography library.

Robust and flexible VPN network tunnelling. OpenVPN is a robust and highly flexible tunneling application that uses all of the encryption, authentication, and certification features of the OpenSSL library to securely tunnel IP networks over a single TCP/UDP port. Consider VPN network as private and assign VPN interface to LAN zone to minimize firewall setup. Allow access to VPN server from WAN zone. # Configure firewall uci rename firewall. @ zone [0] = "lan" uci rename firewall. @ zone [1] = "wan" uci rename firewall. @ forwarding [0] = "lan_wan" uci del_list firewall.lan.device= " ${OVPN_DEV} " uci add_list firewall.lan.device= " ${OVPN_DEV} " uci -q
