How to Append Rules to the NAT Rules

1. Assume a role that includes the IP Filter Management rights profile, or become superuser.

   You can assign the IP Filter Management rights profile to a role that you create. To create the role and assign the role to a user, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

2. Use one of the following methods to append rules to the active rule set:

   • Append rules to the NAT rule set at the command line using the ipnat -f - command.

     # echo "map dmfe0 192.168.1.0/24 -> 20.20.20.1/32" | ipnat -f -

   • Perform the following commands:

     1. Create additional NAT rules in a file of your choice.

     2. Add the rules you have created to the active NAT rules.

        # ipnat -f filename

        The rules in filename are added to the end of the NAT rules.
