SNMP over the WAN (LAN works)
There are two main types of IPv6 WAN connectivity: native (
Auto
and
Static
) and tunneling over IPv4 (
6to4
,
6in4
, and
6rd
).
Native
– (
Auto
and
Static
) The upstream ISP routes IPv6 packets directly.
IPv6 tunneling
– (
6to4
,
6in4
, and
6rd
) Each IPv6 packet is encapsulated by the router in an IPv4 packet and routed over an IPv4 route to a tunnel endpoint that
decapsulates it and routes the IPv6 packet natively. The reply is encapsulated by the tunnel endpoint in an IPv4 packet and routed back over an IPv4 route. Some
tunnel modes do not require upstream ISPs to route or even be aware of IPv6 traffic at all. Some modes are utilized by upstream ISPs to simplify the configuration
and rollout of IPv6.
Enable IPv6 and select the desired IPv6 connection method for this WAN interface.
Disabled
(default) – IPv6 disabled on this interface.
Auto
– IPv6 will use automatic connection settings (if available).
Static
– Input a specific IPv6 address for your WAN connection. This is provided by the ISP if it is supported.
6to4 Tunnel
– Encapsulates the IPv6 data and transfers it to an automatic tunnel provider (if your ISP supports it).
6in4 Tunnel
– Encapsulates the IPv6 data and sends it to the configured tunnel provider.
6rd Tunnel
(
IPv6 rapid deployment
) – Encapsulates the IPv6 data and sends it to a relay server provided by your ISP.
When you configure IPv6, you have the option to designate
DNS Servers
and
Delegated Networks
. Because of the dual-stack setup, these settings are optional: when
configured for IPv6, the router will fall back to IPv4 settings when necessary.
DNS Servers
Each WAN device is required to connect IPv4 before connecting IPv6. Because of this, DNS servers are optional, as most IPv4 DNS servers will respond with AAAA records
(128-bit IPv6 DNS records, most commonly used to map hostnames to the IPv6 address of the host) if requested. If no IPv6 DNS servers are configured, the system will fall
back to the DNS servers provided by the IPv4 configuration.
Delegated Networks
A delegated network is an IPv6 network that is inherently provided by or closely tied to a WAN IP configuration. The IPv6 model is for each device to have end-to-end IP
connectivity without relying on any translation mechanism. In order to achieve this, each client device on the LAN network needs to have a publicly routable IPv6 address.
Auto
IPv6 auto-configuration mode uses DHCPv6 and/or SLAAC to configure the IPv6 networks. When you select
Auto
, all of the following settings are optional (depending on
your provider’s requirements):
PD Request Size
– Prefix Delegation request size. This is the size of IPv6 network that will be requested from the ISP to delegate to LAN networks. (Default: 63)
Primary IPv6 DNS Server
– (optional) Depending on your provider, this may be required. This only takes effect if the default global DNS setting on the
Network
Settings
→
DNS
page is "Automatic".
Additional IPv6 DNS Server
– Secondary DNS server.
Delegated IPv6 Network
– (optional) Network available for delegation to LANs. Depending on your provider, this may be required. Prefixes specified here only
take effect if those supplied by the connection are insufficient to configure your LANs.
Delegated IPv6 Network
– Additional network available for delegation to LANs.
