LABEL DESCRIPTION
IPv6 Connection
Type
IPv6 Rapid Deployment (6rd) is used when the local network uses IPv6 and the ISP has
an IPv4 network. When the NBG-418N v2 has a WAN IPv4 address, 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.
6rd Settings

Border Relay router and connecting to the native IPv6 Internet.
