 ## Configure ExpressRoute FastPath 
 You can enable [ExpressRoute FastPath](expressroute-about-virtual-network-gateways.md) if your virtual network gateway is Ultra Performance or ErGw3AZ. FastPath improves data path performance such as packets per second and connections per second between your on-premises network and your virtual network. 
 
+> [!NOTE]
+> When you enable FastPath on new or existing connections, the Gateway bypass is enabled after the ExpressRoute Gateway and Circuit connection is established. This will briefly route the on-premises traffic through the gateway.
