Abstract
The invention is directed to providing a centralized synchronization method for redundant network elements and is particularly advantageous to routers providing network address translation (NAT) services requiring static port forwarding provisioning. Synchronization is provided by a network management system which can handle one or more backup routers or other network elements using a control protocol different from the control protocol used by the active router.
