About the DS-Lite Page


You are here: Configure > Network > DS-Lite.

Use this page to configure Dual-Stack Lite (DS-Lite). DS-Lite allows service providers to migrate to an IPv6 access network without changing end-user software. The device that accesses the Internet remains the same, thus allowing IPv4 users to continue accessing IPv4 Internet content with minimum disruption to their home networks, while enabling IPv6 users to access IPv6 content.

Softwire initiator for the DS-Lite home router, encapsulates the IPv4 packet and transmits it across an IPv6 tunnel. Softwire concentrator for DS-Lite carrier-grade Network Address Translation (NAT), decapsulates the IPv4-in-IPv6 packet and also performs IPv4-IPv4 NAT translations.
