 # Internet connectivity design considerations 
@@ -66,6 +66,9 @@ The option that you select depends on the following factors:
 - There are scale limits on how many Azure Public IPv4 addresses can be allocated to a Network Virtual Appliance running in native Azure or provisioned on Azure Firewall.  The Azure Public IPv4 address to NSX-T Data Center Edge option allows for much higher allocations (1,000s versus 100s).
 - Use an Azure Public IPv4 address to the NSX-T Data Center Edge for a localized exit to the internet from each private cloud in its local region. Using multiple Azure VMware Solution private clouds in several Azure regions that need to communicate with each other and the internet, it can be challenging to match an Azure VMware Solution private cloud with a security service in Azure. The difficulty is due to the way a default route from Azure works.
 
+> [!IMPORTANT]
+> By design, Public IPv4 Address with NSX-T Data Center does not allow the exchange of Azure/Microsoft owned Public IP Addresses over ExpressRoute Private Peering connections. This means you cannot advertise the Public IPv4 addresses to your customer vNET or on-premises network via ExpressRoute.  All Public IPv4 Addresses with NSX-T Data Center traffic must take the internet path even if the Azure VMware Solution private cloud is connected via ExpressRoute. For more information, visit [ExpressRoute Circuit Peering]: ../expressroute/expressroute-circuit-peerings.

+When connecting **production** Azure VMware Solution private clouds to an Azure virtual network, an ExpressRoute virtual network gateway with the Ultra Performance Gateway SKU should be used with FastPath enabled to achieve 10Gbps connectivity. Less critical environments can use the Standard or High Performance Gateway SKUs for slower network performance.
