NBG6617 User’s Guide

IPv6 Tunneling Select None to not allow IPv6 packets to cross IPv4 networks.

Select 6RD to enable 6RD. IPv6 Rapid Deployment (6RD) is an IPv6 transitioning

process for stateless tunneling of IPv6 over IPv4. Enable 6RD to allow tunneling across

an ISP's IPv4 only access network.

Select 6to4 to transmit IPv6 packets over an IPv4 network. A 6to4 relay router is

required to route 6to4 packets to a native IPv6 network.

Select 6in4 if the NBG6617 has a public IPv4 address and you want to transmit your

IPv6 packets to one and only one remote site whose LAN network is also an IPv6

network. You must know the WAN IP address of the remote gateway.

6RD

The NBG6617 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

NBG6617 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 IPv4/IPv6 field.

Automatically

configured by

DHCPC

Select this to have the NBG6617 detect the relay server’s IP address automatically

through DHCP.

Manually Configured Select this if you have the IPv4 address of the relay server.

Border Relay IPv4

Address

Specify the relay server’s IPv4 address.

Service Provider

IPv6 Prefix

Enter an IPv6 prefix for tunneling IPv6 traffic to the ISP’s Border Relay router and

connecting to the native IPv6 Internet.

Service Provider

IPv6 Prefix length

Enter the 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.

6to4

The NBG6617 should get a public IPv4 address for the WAN. The NBG6617 adds an IPv4 IP header to an IPv6

packet when transmitting the packet to the Internet. In reverse, the NBG6617 removes the IPv4 header from

an IPv6 packet when receiving it from the Internet.

This is available only when you select IPv4 Only in the IPv4/IPv6 field.

Relay Server IPv4

Address

Enter the IPv4 address of a 6to4 relay server which helps forward packets between

6to4 networks and native IPv6 networks.

6in4

The NBG6617 encapsulates IPv6 packets within IPv4 packets across the Internet. You must know the WAN IP

address of the remote gateway device. This mode is normally used for a site-to-site application such as two

branch offices.

This is available only when you select IPv4 Only in the IPv4/IPv6 field.

Remote IPv4

Address

Enter the IPv4 address of the remote gateway to which this interface tunnels traffic.

Remote IPv6

Address

Enter the IPv6 address of the remote gateway to which this interface tunnels traffic.

Local IPv6 Address Enter the IPv6 address assigned by your ISP.

IPv6 Prefix Enter the IPv6 prefix for this interface if you want to use a static IP address.
