What command would be used as part of configuring NAT or PAT to identify an interface as part of the external global network?

  • access-list 10 permit 172.19.89.0 0.0.0.255
  • ip pat inside
  • ip nat inside
  • ip nat outside
Explanation & Hint:

The command used as part of configuring Network Address Translation (NAT) or Port Address Translation (PAT) to identify an interface as part of the external global network is:

  • ip nat outside

This command is applied to the interface that connects to the external network, typically the internet, marking it as the outside interface in the context of NAT or PAT. Traffic leaving this interface will be translated to an address or port that is routable on the external network.

Here’s a brief explanation of the other options:

  1. access-list 10 permit 172.19.89.0 0.0.0.255: This is an access control list (ACL) command used to permit traffic from the 172.19.89.0 network. ACLs can be used in NAT configurations to define which local addresses are allowed to be translated.
  2. ip pat inside: This is not a valid command. The correct command for identifying an interface as part of the internal network in the context of PAT would be ip nat inside, which would be used on the internal interface facing the local network.
  3. ip nat inside: This command is used to designate an interface as part of the internal network that connects to private local network resources in a NAT or PAT configuration.
