LABEL DESCRIPTION
Obtain an IP Select this option If your ISP did not assign you a fixed IP address. This is the default
Address selection.
Automatically
Static IP Address Select this option If the ISP assigned a fixed IP address.
IP Address Enter your WAN IP address in this field if you selected Static IP Address.
Subnet Mask Enter the Subnet Mask in this field.
Gateway IP Enter a Gateway IP Address (if your ISP gave you one) in this field.
Address
MTU Size Enter the MTU (Maximum Transmission Unit) size for each packet. If a larger packet
arrives, the NBG6616 divides it into smaller fragments.
6RD
Use IPv6 Rapid Deployment (6rd) when the local network uses IPv6 and the ISP has an IPv4 network. When
the NBG6616 has an IPv4 WAN address and you set IPv6/IPv4 mode to IPv4 Only, you can enable 6rd to
encapsulate IPv6 packets in IPv4 packets to cross the ISP's IPv4 network.
The NBG6616 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
NBG6616 uses its configured IPv4 WAN IP to route IPv4 traffic to the IPv4 Internet.
This is available only when you select IPv4 Only in the IPv6/IPv4 field.
Enable 6RD Enable IPv6 rapid deployment to tunnel IPv6 traffic from the local network through the
ISP's IPv4 network.
Automatically Select this to have the NBG6616 detect the relay server's IP address automatically
configured by through DHCP.
DHCPC
Manually Configured Select this if you have the IPv4 address of the relay server.
Border Relay IPv4 Specify the relay server's IPv4 address.
Address
Service Provider Enter an IPv6 prefix for tunneling IPv6 traffic to the ISP's Border Relay router and
IPv6 Prefix connecting to the native IPv6 Internet.
Service Provider Enter the IPv6 prefix length.
IPv6 Prefix length
An IPv6 prefix length specifies how many most significant bits (starting from the left) in
the address compose the network address.
IPv4 mask length Enter the subnet mask number (1~32) for the IPv4 network.
DNS Server
First DNS Server Select Obtained From ISP if your ISP dynamically assigns DNS server information
(and the NBG6616's WAN IP address). The field to the right displays the (read-only)
Second DNS Server
DNS server IP address that the ISP assigns.
Third DNS Server
Select User-Defined if you have the IP address of a DNS server. Enter the DNS
server's IP address in the field to the right.
Select None if you do not want to configure DNS servers. If you do not configure a DNS
server, you must know the IP address of a computer in order to access it.
WAN MAC Address The MAC address section allows users to configure the WAN port's MAC address by
either using the NBG6616's MAC address, copying the MAC address from a computer on
your LAN or manually entering a MAC address.
Factory default Select Factory default to use the factory assigned default MAC Address.
Clone the Select Clone the computer's MAC address - IP Address and enter the IP address of
computer's MAC the computer on the LAN whose MAC you are cloning.
