Interface Setup – LAN
In this field, users can map the specific IP (must in the DHCP IP pool) for some specific MAC, and this
information can be listed in the following table.
IP Address: Enter the specific IP. For example: 192.168.1.110.
MAC Address: Enter the responding MAC. For example: 00:0A:F7:45:6D:ED
When added, you can see the ones listed as showed below:
IPv6 Parameters
The IPv6 address composes of two parts, thus, the prefix and the interface ID.
Interface Address / Prefix Length: Enter a static LAN IPv6 address. If you are not sure what to do
with this field, please leave it empty as if contains false information it could result in LAN devices not
being able to access other IPv6 device. Router will take the same WAN's prefix to LAN side if the field
is empty.
DHCPv6 Server
There are two methods to dynamically configure IPv6 address on hosts, Stateless and Stateful.
Stateless auto-configuration requires no manual configuration of hosts, minimal (if any)
configuration of routers, and no additional servers. The stateless mechanism allows a host to generate
its own addresses using a combination of locally available information (MAC address) and information
(prefix) advertised by routers. Routers advertise prefixes that identify the subnet(s) associated with a
link, while hosts generate an "interface identifier" that uniquely identifies an interface on a subnet. An
address is formed by combining the two. When using stateless configuration, you needn't configure
anything on the client.
Stateful configuration, for example using DHCPv6 (which resembles its counterpart DHCP in IPv4.)
In the stateful auto configuration model, hosts obtain interface addresses and/or configuration
information and parameters from a DHCPv6 server. The Server maintains a database that keeps track
of which addresses have been assigned to which hosts.
DHCPv6 Server: Check whether to enable DHCPv6 server.
DHCPv6 Server Type: Select Stateless or Stateful. When DHCPv6 is enabled, this parameter is
