IPsec XAuth from Android to Vigor Router

IPsec is very secure and delivers great performance, and since 2018, Vigor Router also provides IPsec Xauth. If you are not comfortable with every VPN client using the same pre-shared key, you can use IPsec Xauth instead. IPsec Xauth authenticates the VPN clients not only by a pre-shared key but also a unique username and password. This article demonstrates how to set up Vigor Router as a VPN server for IPsec Xauth clients, and the configuration required on an Android device to establish the VPN.
