IPv6 parameters
Interface Address / Prefix Length: enter the static LAN IPv6 address, we suggest leave the field empty
because when setted wrong, it will result in LAN devices not being able to access other IPv6 device through
internet. Router will take the same WAN's prefix to LAN side if the field is empty.
MLD Snooping: Similar to IGMP Snooping, but applicable for IPv6.
DHCPv6 Server
DHCPv6 Server: Check whether to enable DHCPv6 server.
DHCPv6 Server Type: Select Stateless or Stateful. When DHCPv6 is enabled, this parameter is available.
Stateless: If selected, the PCs in LAN are configured through RA mode, thus, the PCs in LAN are
configured through RA mode, to obtain the prefix message and generate an address using a
combination of locally available information (MAC address) and information (prefix) advertised by
routers, but they can obtain such information like DNS from DHCPv6 Server.
Stateful: If selected, the PCs in LAN will be configured like in IPv4 mode, thus obtain addresses and
DNS information from DHCPv6 server.
Start interface ID: enter the start interface ID. The IPv6 address composed of two parts, thus, the prefix and the
interface ID. Interface is like the Host ID compared to IPv4.
End interface ID: enter the end interface ID.
Leased Time (hour): the leased time, similar to leased time in DHCPv4, is a time limit assigned to clients, when
expires, the assigned ID will be recycled and reassigned.
Issue Router Advertisement: Check whether to enable issue Router Advertisement feature. It is to send
Router Advertisement messages periodically. Router will multicast the v6 Prefix information (similar to v4
network number 192.168.1.0) to all LAN devices if the field is enabled. We suggest enabling this field.
