The following table describes the labels in this screen.
Table 37 Network > WAN > IPv6 (6rd)
LABEL DESCRIPTION
IPv6 Connection IPv6 Rapid Deployment (6rd) is used when the local network uses IPv6 and the ISP has
Type an IPv4 network. When the NBG-418N v2 has an IPv4 WAN address and you set IPv6/
IPv4 mode to IPv4 only, you can enable 6rd to encapsulate IPv6 packets in IPv4 packets
to cross the ISP's IPv4 network.
The NBG-418N v2 generates a global IPv6 prefix from its IPv4 WAN address and tunnels
IPv6 traffic to the ISP's border relay router to connect to the native IPv6 Internet. The
local network can also use IPv4 services. The NBG-418N v2 uses its configured IPv4
WAN IP to route IPv4 traffic to the IPv4 Internet.

Enable Click Enable Autoconfiguration if you want the devices on your local area network to
Autoconfiguration obtain network address that are not managed by a DHCPv6 server.
Autoconfiguration Select SLAAC + Stateless DHCPv6 if you want the interface to automatically generate
Type a link-local address via stateless autoconfiguration.
Select Stateful(DHCPv6) when the devices connected to your LAN needs to have their
TCP/IP configuration set to DHCPv6 or obtain an IPv6 address automatically.
