IPv6
From the
Administration > Network > IPv6
window, you can configure IPv6. The
system NAS supports IPv6 connectivity with stateless address configurations.
Router Advertisement Daemon (RADVD) is also available for sending out router
advertisements described in RFC 2461 for IPv6. Hosts within the same network
can automatically configure their addresses. This option should be used when the
network router is configured as dual stack (IPv4 and IPv6). The router will send the
advertisement. Newer clients such as Windows 7, Vista, MAC OS 10.5 (and
greater) will benefit from IPv6, as they will query DNS via IPv6 first and then IPv4.
The latest browsers such as IE8, Safari 4, and Firefox prefer IPv6 DNS but will fall
back to IPv4 if IPv6 fails. This setting also needs to be applied on the router.
