help Azure VPN Gateway FAQ
What does Azure VPN Gateway connect?
Azure VPN Gateway connects Azure virtual networks to on-premises networks, other Azure VNets, or individual clients. It commonly uses IPsec and IKE tunnels for encrypted traffic.
When should I use Azure VPN Gateway instead of ExpressRoute?
VPN Gateway runs encrypted tunnels over the public internet, which makes it easier and cheaper to start. ExpressRoute uses a private connectivity provider circuit and is usually chosen for higher predictability, compliance, or large enterprise networking.
Does Azure VPN Gateway support point-to-site VPN?
Yes. Point-to-site VPN lets individual devices connect into an Azure virtual network without requiring a site-to-site appliance at the user's location.
What is active-active mode in Azure VPN Gateway?
Active-active mode uses two gateway instances with separate public IP addresses. It is commonly paired with BGP and compatible on-premises VPN devices for higher availability.
