A second interface has a second address and a second port number. A router is in communication with the first and second interfaces over a network. The router is configured to request, a first set of failover information from the first interface. The router is further configured to receive the first set of failover information from the first interface. The first set of failover information includes the second address and the first port number. The router is configured to detect a failure on the first interface. The router is further configured to modify a network access translation (NAT) table stored within the router by replacing the first address of the first interface with the second address of the second interface while retaining the first port number, such that the first port number remains unchanged."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reverse network address translation failover","description":"In an example system, a first interface has a first address and a first port number.
