I can never get L2TP/IPSec to work reliably on Windows 10 to connect to my Unifi setup. My Macs always connect reliably and with ease. Are there any alternatives for VPN clients other than the built in one for Windows 10?

Layer 2 Tunneling Protocol (L2TP): L2TP is the industry standard when setting up secure VPN tunnels. L2TP supports either computer certificates or a Pre-shared key as the authentication method for IPsec. L2TP/IPsec VPN connections provide data confidentiality, data integrity, and data authentication.

The reason people use L2TP is due to the need to provide login mechanism to users. IPSec by itself is meant to by a tunneling protocol in a gateway-to-gateway scenario (there are still two modes, tunnel mode & transport mode). So vendors use L2TP to allow people to use their products in client-to-network scenario. 1- Configuring a new VPN L2TP/IPSec connection with the Windows 7 native client. 2- Connect to the VPN. 3- Disconnect from the VPN. 4- If you experience problems with your VPN connection. 1- Configuring a new VPN L2TP/IPSec connection with the Windows 7 native client. Steps: 1- Open the "Network and Sharing Center".

IPsec is used to secure L2TP packets. The initiator of the L2TP tunnel is called the L2TP Access Concentrator (LAC). L2TP and IPsec is supported for native Windows XP, Windows Vista and Mac OSX native VPN clients. However, in Mac OSX (OSX 10.6.3, including patch releases) the L2TP feature does not work properly on the Mac OS side.

Dec 29, 2012 · L2TP is considered to be a more secure option than PPTP, as the IPSec protocol which holds more secure encryption algorithms, is utilized in conjunction with it. It also requires a pre-shared certificate or key. L2TP’s strongest level of encryption makes use of 168 bit keys, 3 DES encryption algorithm and requires two levels of authentication. IPsec is often used to secure L2TP packets by providing confidentiality, authentication and integrity. The combination of these two protocols is generally known as L2TP/IPsec (discussed below). The two endpoints of an L2TP tunnel are called the LAC (L2TP Access Concentrator) and the LNS (L2TP Network Server). The LNS waits for new tunnels.

Since L2TP doesn’t have any encryption or authentication capabilities (both are key features of VPNs) on its own, IPSec VPN is often paired with it. The framework is also used to provide security for other protocols such as IKEv2.
