11.6.3 Subnets and dynamic NAT or dynamic PAT

Note the following subnet and dynamic NAT and dynamic PAT considerations:

Subnets are unique to tenants (a subnet does not span multiple tenants). The benefit of subnets is that the same subnet can be used by different tenants.
Subnet filters use tenant and address pairs.
If subnet connection rules are configured, they apply to all tenants. The subnet members must be unique in all tenants (a node is assigned to only one tenant). You can use subnet connection rules to establish a link between a tenant and the default tenant. This feature is supported only when one of the two linked tenants is the default tenant.
