Client-to-Site VPN: Scenario 1
When the remote user’s laptop or PC works as the VPN client, the laptop or PC uses a VPN client
software program to create VPN tunnels between itself and the VPN server. The VPN client
software program can use L2TP, PPTP, IPsec, or OpenVPN as the tunneling protocol.

Note:
In scenario 1, you need to configure VPN client and VPN server separately on the gateways, while remote hosts can access the local
networks without running VPN client software.
In scenario 2, you need to configure VPN server on the gateway, and then configure the VPN client software program on the remote
user’s laptop or PC, while the remote user’s gateway doesn’t need any VPN configuration.
