PreSharedIPSecKey Property of the IFPCVpnConfiguration Interface

The PreSharedIPSecKey property gets or sets the preshared IPsec key for incoming L2TP connections. A preshared key is a string of text that is configured on both the VPN client and the VPN server. A preshared key provides a relatively weak authentication method. Therefore, we recommend using it only in the interim when your public key infrastructure (PKI) is being deployed to obtain computer certificates, or when a preshared key is required by VPN clients.
