The Route Table and Network ACL tabs allow you to view the associated route table and NACL with the subnet and make changes as necessary.
The following screenshot shows a default route (local) with another route pointing to an IGW. Routing will be covered in more detail in the Route tables section of this chapter:
In the following NACL, we can see two rules, including a default rule denying ALL traffic to the subnet that doesn't meet any other rules in the access control list. NACLs are covered in more detail in a later section of this chapter titled Network access control lists:
It's worth pointing out at this stage that a subnet can only be associated with a single NACL and a single route table, but multiple subnets can share the same NACL and route table. I will cover more on both of these components in the upcoming sections in this chapter.
