Other Azure regions are on the roadmap.
 * Palo Alto Networks Cloud NGFW can't be deployed with Network Virtual Appliances in the Virtual WAN hub.
-* For routing between Virtual WAN and Palo Alto Networks Cloud NGFW to work properly, your entire network (on-premises and Virtual Networks) must be within RFC-1918 (subnets within 10.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12). For example, you may not use a subnet such as 40.0.0.0/24 within your Virtual Network or on-premises. Traffic to 40.0.0.0/24 may not be routed properly.  
 * All other limitations in the [Routing Intent and Routing policies documentation limitations section](how-to-routing-policies.md) apply to Palo Alto Networks Cloud NGFW deployments in Virtual WAN.

 ### Troubleshooting Routing intent and policies
 
 * Ensure Cloud NGFW deployment is completed successfully before attempting to configure Routing Intent.
-* Ensure all your on-premises and Azure Virtual Networks are in RFC1918 (subnets within 10.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12).
