Embodiments include a gateway coupled to a protected network, an external network, and a name server. The name server, in response to a hostname lookup request, configured to provide a network device with the internal address; and the gateway with a mapping including the internal address, the addresses of the device, and the hostname. The gateway configured to rewrite destination addresses of outbound packets, and source addresses of inbound packets, based on the mapping."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Destination address rewriting to block peer-to-peer communications","description":"Systems and methods for protecting a network including providing a mapping between internal addresses as seen by devices of the protected network and external addresses; providing devices with a mappe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9723023","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
