+When defining a NACL rule, you must enter the following settings:
 
 - **IP version**: Either IPv4 or IPv6. The rule will apply only to traffic matching this IP version, meaning that in effect, each VPC has two NACLs: one for IPv4 and one for IPv6. If you want to create an equivalent rule for the other IP version, you must do so separately.
