Abstract
In general, embodiments of the invention relate to a method and system for enabling a peer state synchronization mechanism for dynamic network address translation (DNAT). More specifically, at least two network elements may be permitted to mount each other's DNAT tables, thereby providing redundancy for the implementation of DNATs in case of the failover of one of the network elements. The failed network element may then re-initialize while the functional network element continues to process packets, including packets that have been redirected to the functional network element post-failure of the failed network element. Upon completing re-initialization, the once failed network element recovers its DNAT table from the functional network element and proceeds to process packets normally.
