To configure an ISA-NAT group

Purpose

Perform this procedure to configure an ISA-NAT group on supported 7750 SR devices. An ISA-NAT group provides a redundant NAT function for routing instances using ISA broadband applications MDAs or ESA VMs.

Steps
 

In the navigation tree Equipment view, expand Network→NE→Logical Group.


Right-click on the ISA-NAT Groups object and choose Create ISA-NAT Groups or select an existing ISA-NAT Group and click Properties. The ISA-NAT Group (Create|Edit) form opens.


Configure the parameters, as required.

The Redundancy and Failed MDA Limit parameters can be configured only when the Administrative State parameter is set to Down.


Select an ISA RADIUS policy. See To configure an ISA RADIUS policy for information about how to configure a ISA RADIUS policy.


Click Apply. The ISA-NAT Group form refreshes with additional tabs and parameters.


When the Hardware Type parameter is set to ISA, perform the following steps:

  1. Click on the ISA-NAT MDA tab.

  2. Click Create.The ISA-NAT Group MDA (Create) form opens.

  3. Select an ISA Broadband Applications MDA. See To configure an MDA for information about how to configure an MDA.

    NOTE: You can configure up to six ISA-NAT group members. Each group member must be an ISA Broadband Applications MDA

  4. Click on the General tab and configure the Administrative State parameter.

    NOTE: You can set the Administrative State parameter to Up only when the ISA-NAT group contains at least one MDA and when the Active MDA Limit parameter is set to a value greater than 0.

  5. Click on the Dynamic MDA tab.

  6. Click Create. The Dynamic MDA (Create) form opens.

  7. Configure the required parameters.


When the Hardware Type parameter is set to ESA VM, perform the following steps:

  1. Click on the NAT ESA VM tab.

  2. Click Create. The NAT ESA VM (Create) form opens.

  3. Select an ESA ID and an ESA VM ID.


Save your changes and close the forms.
