You must configure gateway GW1 to satisfy the network security requirements for point-to-site (P2S) VPN users. In GW1's Point-to-site configuration, which Tunnel type should you select?

OpenVPN (SSL) is the correct choice because it offers robust security, cross-platform compatibility, and can traverse firewalls effectively, making it ideal for P2S VPN scenarios. Azure VPN Gateway supports OpenVPN, providing a flexible and secure solution for remote users. IKEv2 is also a strong option for P2S, but OpenVPN (SSL) is generally preferred for its broader client support and ability to use TCP port 443, which is often open. SSTP (SSL) is a Windows-specific protocol and less versatile for diverse client environments. IKEv2 alone or in combination with SSTP would limit compatibility or security compared to OpenVPN.
