Static IP List

The specified IP will be assigned to the corresponding MAC Address listed in the following table when

DHCP Server assigns IP Addresses to Clients.

Press Add to the Static IP List.

Enter the MAC Address, IP Address, and then click Apply to confirm your settings. But the IP assigned

should be outside the range of 192.168.0.100-192.168.0.199.

IP Alias

This function allows the creation of multiple virtual IP interfaces on this router. It helps to connect two

or more local networks to the ISP or remote node.

IP Alias

: Check whether to enable this function.

IP Address

: Specify an IP address on this virtual interface.

Subnet Mask

: Specify a subnet mask on this virtual interface. Click Apply to apply your settings.

IPv6 Autoconfig

The IPv6 address composes of two parts, the prefix and the interface ID.

There are two ways to dynamically configure IPv6 address on hosts. One is “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.

The second way is “stateless” configuration. 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.

Group Name:

Here group refers to the group you set in Interface Grouping section, you can set the

parameters for the specific group. Select the group by the drop-down box. For more information please

refer to Interface Grouping of this manual.

Static LAN IPv6 Address Configuration

Interface Address / Prefix Length

: Enter the static LAN IPv6 address.

IPv6 LAN application

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.

Note

: Interface ID does NOT support ZERO COMPRESSION "::". Please enter the complete

information. For example: Please enter "0:0:0:2" instead of "::2".

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.

ULA Prefix Advertisement

: Enable this parameter to include the ipv6 ULA address in the RA

messages. ULA, unique local address, is an IPv6 address in the block fc00::/7. It is approximately the

IPv6 counterpart of the IPv4 private address. They are not routable in the global IPv6 Internet.

RADVD Type

: The way that ULA prefix is generated.

i

Randomly Generated

i

Statically Configured: select to set manually in the following parameters.

Prefix

: Set the prefix manually.

Preferred Life Time

: The ULA prefix life time. When the time is over, the ULA prefix is invalid any

more, -1 means no limit.

Valid Life Time

: It is a time threshold, when the time is over, clients should obtain new IPv6 address

from the router through RA; -1 means to be limitless.

MLD snooping

: Similar to IGMP snooping, listens in on the MLD conversation between hosts and

routers by processing MLD packets sent in a multicast network, and it analyzes all MLD packets

between hosts and the connected multicast routers in the network. Without MLD snooping, multicast

traffic is treated in the same manner as broadcast traffic - that is, it is forwarded to all ports. With MLD

snooping, multicast traffic of a group is only forwarded to ports that have members of that group.

i

Standard Mode: In standard mode, multicast traffic will flood to all bridge ports when no

client subscribes to a multicast group.

i

Blocking Mode: In blocking mode, the multicast data will be blocked when there is no

client subscribes to a multicast group, it won’t flood to the bridge ports.

Stateless and Stateful IPv6 address Configuration

Stateless: Two methods can be carried.

i

With DHCPv6 disabled, but Issue Router Advertisement Enabled

With this method, 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.

i

With both DHCPv6 and Issue Router Advertisement Enabled

With this method, the PCs’ addresses in LAN are configured like above method, but they can obtain

such information like DNS from DHCPv6 Server.

Page 39 / 169

39

Stateful: two methods can be adopted.

i

With only DHCPv6 enabled

With this method, the PCs’ addresses are configured the same as in IPv4, that is addresses are

assigned by DHCPv6 server.

i

With both DHCPv6 and Issue Router Advertisement Enabled

With

this

method,

the

PCs’ addresses

are

the

like

above,

information in RA packets will be neglected.

Interface Grouping

Interface grouping is a function to group interfaces, known as VLAN. A Virtual LAN, commonly known

as a VLAN, is a group of hosts with the common set of requirements that communicate as if they were

attached to the same broadcast domain, regardless of the physical location. A VLAN has the same

attributes as a physical LAN, but it allows for end stations to be grouped together even if they are not

located on the same network switch.

Each group will perform as an independent network. To support this feature, you must create mapping

groups with appropriate LAN and WAN interfaces using the Add button.

(Please Note: P4 can be configured as EWAN, and when the device is in EWAN profile, there is no

P4/EWAN interface as P4 is working as a WAN port.)

Group Isolation

: If enabled, devices in one group are not able to access those in the other group.
