 You can enable network policies either for network security groups only, for user-defined routes only, or for both.
 
-If you enable network security policies for user-defined routes, you can use a custom address prefix length (subnet mask) equal to or larger than the virtual network address space prefix length to invalidate the /32 default route propagated by the private endpoint. This capability can be useful if you want to ensure that private endpoint connection requests go through a firewall or virtual appliance. Otherwise, the /32 default route sends traffic directly to the private endpoint in accordance with the [longest prefix match algorithm](../virtual-network/virtual-networks-udr-overview.md#how-azure-selects-a-route).

-> To invalidate a private endpoint route, user-defined routes must have a prefix size that is equal to or smaller than the virtual network address space where the private endpoint is provisioned. For example, a user-defined routes default route (0.0.0.0/0) won't invalidate private endpoint routes because it covers a broader range than the private endpoint's address space. The longest prefix match rule gives higher priority to more specific address prefixes. Additionally, ensure that network policies are enabled in the subnet hosting the private endpoint.
