Site-to-Site (or Gateway-to-Gateway) VPN and Remote access (client-to-site) VPN are two
distinct types of VPNs. Where client-to-site VPN represents a single user connection,
site-to-site VPNs deal with remote connections between entire networks.
In a site-to-site VPN, the IPSec security method is used to create an encrypted tunnel
from one customer network to a remote site of the customer. Palo Alto Networks VPN
tunnels can also be used between partners.
In remote access VPN, individual endpoints are
connected to a private network to access the services and resources of that private
network remotely. Remote Access VPN is most suitable for the business and home users as
it allows multiple endpoints.
