Enter the IPv6 address on the WAN side in this field.
Subnet Prefix
Length
Enter the address prefix length to specify how many most significant bits in an IPv6
address compose the network address.
Default Gateway
Enter the IP address of the next-hop gateway. The gateway is a router or switch on the
same segment as your NBG-418N v2's interface(s). The gateway helps forward packets
to their destinations.

Router
Advertisement
Lifetime
If you select

Lifetime
which is the 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)
