LABEL
DESCRIPTION
IPv6 Connection
Type
IPv6 in IPv4 Tunnel
is the encapsulation of IPv6 packets in IPv4 packets so that IPv6
packets can be sent over an IPv4 infrastructure.

Address
Enter the IPv4 IP address of the device on a remote network.
Remote IPv6
Address
Enter the IPv6 IP address of the device on a remote network.

IPv6 DNS Settings
Primary and
Secondary DNS
Address
Enter the first/second IPv6 DNS server address assigned by the ISP.
Lan IPv6 Address Settings
LAN IPv6 Address
Enter the IPv6 address for the LAN port in this field.
LAN IPv6 Link-Local
Address
This shows the IPv6 Link-local address in the LAN side. This is used by routers when
communicating with neighboring devices on the same link. It allows IPv6-capable
devices to communicate with each other in the LAN side.i

If you select
SLAAC + Stateless DHCPv6
, type in the
Router Advertisement
Lifetime
which is amount of time in minutes that a device may have an IPv6 address
before it is required to renew the lease.

Range(Start)
If you select
Stateful (DHCPv6)
, specify the range of IPv6 addresses from which the
DHCPv6 server assigns to the clients. Enter the smallest value of the last block of the
IPv6 addresses which are to be allocated.
IPv6 Address
Range(End)
If you select
Stateful (DHCPv6)
, specify the range of IPv6 addresses from which the
DHCPv6 server assigns to the clients. Enter the largest value of the last block of the
IPv6 addresses which are to be allocated.
IPv6 Address

The following table describes the labels in this screen.
Table 42
Network > WAN > IPv6 (6rd)
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
6rd Mode
Click the
6rd DHCPv4
radio button
to have your ISP generate a 6rd DHCPv4 address
automatically. Choose
Manual
to enter a fixed 6rd DHCPv4 address manually.
6rd IPv6 Prefix
Enter an IPv6 prefix and the address prefix length for tunneling IPv6 traffic to the ISP’s
Border Relay router and connecting to the native IPv6 Internet.
IPv4 Address
This shows the NBG-418N v2’s WAN IPv4 address.
Enter the IPv4 subnet mask length (1 to 32) in the
Mask Length
field.
6rd Relay
Enter the ISP’s border relay server’s IPv4 address in this field.
IPv6 DNS Settings
Primary/Secondary
DNS Address
Enter the first/second IPv6 DNS server address assigned by the ISP.
