(Optional) Enabling NAT Service Priority

(Optional) Enabling NAT Service Priority


Some scenarios require a higher priority of the NAT service than that of routing services. In this case, perform NAT first, and search the routing table for the translated addresses to facilitate traffic forwarding. For example, to enable a public network device to access a private network device, configure static NAT first to translate the private IP address into a fixed public IP address and then configure a static route to the public IP address so that traffic sent from the public network to the private network can be distributed through NAT.

Pre-configuration Tasks

Before enabling NAT service priority, complete the following tasks:


  1. Run system-view

    The system view is displayed.

  2. Run nat inside priority enable

    The NAT service has a higher priority than routing services.

    By default, routing services have a higher priority.
