Configuring NAT

Configuring NAT is a four-step process—the steps required to configure an
access control policy (ACP):
1. Enable the firewall on the ProCurve Secure Router.
2. Configure at least one access control list (ACL).
3. Configure the ACP.
4. Assign the ACP to specific interfaces.
For detailed information about configuring ACLs and ACPs, see Chapter 5:
Applying Access Control to Router Interfaces.
