About endpoints

For a BIG-IP® device, the local endpoint is the WAN Optimization Manager™ (WOM®) on the system where you are working. The remote endpoint is the WAN Optimization Manager on another BIG-IP system (on the other side of the WAN), with which the local endpoint interacts. After you identify the endpoints, communication between the WAN Optimization Managers takes place in an iSession™ connection between the two BIG-IP WOM devices.

About local endpoints and high availability

You can configure two BIG-IP® WOM® systems for high availability by setting them up as redundant systems. Both systems must be installed on the same hardware platform. When you configure two BIG-IP WOM systems for high availability, specify the floating IP address as the WAN self IP address of the local endpoint. For WAN optimization, you can use only the active-standby redundancy mode (not the active-active mode). Otherwise, you can set up redundancy as you would for any BIG-IP system.

Customizing local endpoint settings

Typically, you configure the local endpoint using the Quick Start screen. However, if you want to delete or disable the local endpoint, change the IP port, or specify the handling of non-iSession, NAT, or SNAT traffic, you can adjust these settings on the Local Endpoint Properties screen.
Note: You cannot modify the local endpoint IP address. To change it, you must first delete the current local endpoint IP address, and then add a new one.
  1. On the Main tab, click WAN Optimization > Local Endpoint.
  2. Take the action or actions that support your requirements.
    Option Action
    To disable the local endpoint For the State setting, clear the Enabled check box.
    To change the IP port In the Tunnel Port field, type a different number. This is the IP port that the BIG-IP® WOM® uses for control connections. It must be a port that is allowed access through the firewall. The range is from 1 to 65535.
    To handle non-iSession traffic For the No iSession Route setting, select one of the options for handling traffic for which there is no remote endpoint to complete the iSession connection.
    • Passthrough: Specifies that the traffic flow continues without an iSession connection.
    • Drop: Specifies that the traffic flow continues without an iSession connection.
    To disallow NAT traffic Clear the Allow NAT check box.
    To change the SNAT setting From the SNAT list, select an option.
    • None: Indicates that the system uses the original connection client IP address.
    • Local: Indicates that the system uses the endpoint IP address closest to the destination. Use this setting to make sure the return route also goes through the BIG-IP WOM system, so that both sides of the connection can be optimized. This setting is useful if responses returning from the server to the client would not normally pass through the BIG-IP WOM system.
    • Remote: Indicates that the system uses the source IP address of the incoming iSession connection. Use this setting when an appliance that uses NAT is located between the BIG-IP WOM endpoints.
    To delete the local endpoint Click Delete.
  3. Click Update.

About iSession listeners

An iSession listener is a virtual server created on the local endpoint, which terminates iSession™ connections for inbound traffic from the WAN on the specified port. When you use the Quick Start screen to configure WAN Optimization Manager™ (WOM®), the system creates the default iSession listener isession-virtual on the local endpoint, which monitors all incoming traffic (all ports) and terminates iSession connections.

Note: If you delete the system-created isession-virtual listener without creating a new iSession listener, WOM cannot optimize traffic.

Adding iSession listeners

You can add iSession™ listeners for specific application traffic that you want the system to handle differently from the iSession listener that the system creates automatically.
  1. On the Main tab, click WAN Optimization > Local Endpoint > iSession Listeners.
  2. Click the Create button. The New iSession Listener screen opens. The IP Address field displays the IP address of the local endpoint, which cannot be modified on this screen.
  3. In the Name field, type a name for the iSession listener.
  4. For the Port setting, type the service port used by the application, or select an application from the list. When you select from the list, the Port field displays the associated default port.
  5. For the Enabled VLANs setting, specify the VLANs on which this iSession listener listens for incoming traffic. Move the VLANs from the Available list to the Selected list.
  6. From the iSession Profile list, select the iSession profile to associate with this iSession listener.
  7. From the Authentication and Encryption list, select the SSL profile you want the system to use for inbound iSession connections from the WAN that are terminated by this iSession listener. You can use the default values clientssl and wom-default-clientssl to get the WAN Optimization Manager™ up and running, but you need to customize this profile for your production environment.
  8. Click Finished.
