 This article helps you add additional site-to-site (S2S) connections to a VPN gateway that has an existing connection. This architecture is often referred to as a "multi-site" configuration. You can add a S2S connection to a VNet that already has a S2S connection, point-to-site connection, or VNet-to-VNet connection. There are some limitations when adding connections. Check the [Prerequisites](#before) section in this article to verify before you start your configuration.

 This article helps you configure the necessary VPN Gateway point-to-site (P2S) server settings to let you securely connect individual clients running Windows, Linux, or macOS to an Azure VNet. P2S VPN connections are useful when you want to connect to your VNet from a remote location, such as when you're telecommuting from home or a conference. You can also use P2S instead of a site-to-site (S2S) VPN when you have only a few clients that need to connect to a virtual network (VNet). P2S connections don't require a VPN device or a public-facing IP address.

 There are various different configuration options available for P2S. For more information about point-to-site VPN, see [About point-to-site VPN](point-to-site-about.md). This article helps you create a P2S configuration that uses **certificate authentication** and the Azure portal. To create this configuration using the Azure PowerShell, see the [Configure P2S - Certificate - PowerShell](vpn-gateway-howto-point-to-site-rm-ps.md) article. For RADIUS authentication, see the [P2S RADIUS](point-to-site-how-to-radius-ps.md) article. For Azure Active Directory authentication, see the [P2S Azure AD](openvpn-azure-ad-tenant.md) article.
