 * The subnet has a [system default route](/azure/virtual-network/virtual-networks-udr-overview#default) that routes traffic with destination 0.0.0.0/0 to the internet automatically. Once NAT gateway is configured to the subnet, communication from the virtual machines existing in the subnet to the internet will prioritize using the public IP of the NAT gateway.
 
-* You can override NAT gateway as a subnet’s system default route to the internet with the creation of a custom user-defined route (UDR) for 0.0.0.0/0 traffic.
 
-* Presence of User Defined Routes (UDRs) for virtual appliances, VPN Gateway, and ExpressRoute for a subnet's 0.0.0.0/0 traffic causes traffic to route to these services instead of NAT gateway.

 * Outbound connectivity follows this order of precedence among different routing and outbound connectivity methods:
 
-    * UDR with Virtual appliance / VPN Gateway / ExpressRoute >> NAT gateway >> Instance-level public IP address on a virtual machine >> Load balancer outbound rules >> default system route to the internet.
