DS-Lite (Dual Stack Lite, IPoE)
DS-Lite is a connection type used by ISPs to provide internet access to IPv4 networks and services. It can
be WAN, DMZ, or an unassigned LAN port. You can use DS-Lite to carry IPv4 traffic over an IPv6 tunnel
between the gateway and a server.
IPv6 connection types:
n
DHCPv6
n
PPPoE
n
Static IP - WAN, DMZ or unassigned LAN port.
The DS-Lite master WAN connection type must be one of these:
n
Dynamic IPv6
n
Static IPv6
n
PPPoEv6
n
Bridge IPv6
To enable DS-Lite:
1. In the Configuring Internet Connectivity page, click New/Edit the IPv4 connection.
The Edit Internet Connection window opens.
2. For Connection type, select DS-Lite.
Note - Make sure the interface type is the same for both IPv4 and IPv6. For example, if the IPv4 the
interface is configured as WAN, the IPv6 interface must also be configured as WAN.
3. The AFTR address field is displayed.
Note - This field is not mandatory when the IPv6 connection type is DHCPv6.
4. In the Linked connection field, select the IPv6 connection name.
5. In the Advanced tab:
n
Set the default MTU of the DS-Lite interface to 1460 (IPv4 default = 1500)
n
Set the size of the IPv6 header to 40.

IPIP
IPIP, a variation of DS-Lite, is used to tunnel IPv4 traffic over IPv6-only networks. As in DS-Lite, the IPv4
traffic is tunneled over an existing IPv6 connection. The DS-Lite/IPIP tunnel is created between the client
(gateway) and a peer (AFTR which resides on the ISP and is configured statically or acquired via DHCPv6).
IPIP uses the same IPv4-over-IPv6 tunnel as DS-Lite, but you can configure a static IPv4 address, which is
globally routable.
The gateway first establishes an IPv6 connection to the ISP. The IPv6 address consists of:
