5.3 Changing the IP Address of the Access Gateway Appliance

If you need to change the IP address of the Access Gateway machine, you need to configure the Access Gateway for this change. This is especially significant when the Access Gateway Appliance has only one IP address.

IMPORTANT:The new IP address must be configured in the Administration Console before you change it on the Access Gateway. If you change the address on the Access Gateway first, the Administration Console does not trust the Access Gateway and cannot establish communication.

  1. In the Administration Console, click Devices > Access Gateways > Edit > Adapter List.

  2. (Conditional) If the machine belongs to a cluster, select the Access Gateway from the Cluster Member list.

  3. From the Adapter List, select the subnet mask that contains the IP address you want to change.

    When you select the subnet mask, the Adapter page appears.

  4. Select the old IP address, click Change IP Address, specify the new IP address, then click OK.

    This option changes all configuration instances of the old IP address to the new IP address. For example, any reverse proxies that have been assigned the old IP address as a listening address are modified to use the new IP address as the listening address.

  5. To save your changes to browser cache, click OK.

  6. To apply your changes, click the Access Gateways link, then click Update > OK.

  7. If you are physically moving the machine, move it before completing the rest of these steps.

  8. Check the IP address that the Administration Console uses for managing the Access Gateway. Click Access Gateways > [Name of Access Gateway] > Edit.

  9. If the old IP address is listed as the Management IP Address, select the new IP address. If your Access Gateway has multiple IP addresses, select the one that you want the Administration Console to use for communication with the Access Gateway.

    The port should only be modified if there is another device on the Access Gateway that is using the default port of 1443.

  10. If the name of the Access Gateway is the old IP address, modify the Name option.

  11. Click OK.

    The Administration Console uses the configured IP address to find the Access Gateway.

  12. On the Identity Server, restart Tomcat:

    Linux: Enter the following command:

    /etc/init.d/novell-tomcat5 restart

    Windows: Enter the following commands:

    net stop Tomcat5

    net start Tomcat5

If your Access Gateway stops reporting to the Administration Console after completing these steps, you need to trigger an auto-import. See Triggering an Import Retry in the Novell Access Manager 3.1 SP2 Installation Guide.
