PPPoE Client for IPv6

The firewall supports an Ethernet Layer 3 interface or subinterface acting as a Point-to-Point Protocol over Ethernet (PPPoE) IPv6 client.

The firewall supports an Ethernet Layer 3 interface or subinterface acting as a Point-to-Point Protocol over Ethernet (PPPoE) IPv6 client to reach an ISP that provides IPv6 internet services. In PPPoE mode, the interface or subinterface can obtain an IPv6 address dynamically using DHCPv6 either in stateful or stateless mode. In stateful mode, the PPPoE interface acquires all connection parameters dynamically from the DHCPv6 server. In stateless mode, the IPv6 address of the PPPoE interface is obtained using stateless address autoconfiguration (SLAAC), but the other parameters (DNS and prefix delegation) are obtained through DHCPv6. Stateful and stateless DHCPv6 reduce provisioning effort and errors, and simplify address management.

Only Ethernet Layer 3 interfaces and subinterfaces support an IPv6 PPPoE client (tunnel, AE, VLAN, and loopback interfaces don't support an IPv6 PPPoE client). A Layer 3 interface and its subinterface can't act as a PPPoEv6 client at the same time.

A limitation is that the interface configured with PPPoEv6 can't acquire a DNS server address or DNS prefix from Router Advertisement (RA-DNS). You'll have to rely on DHCPv6 to obtain the DNS information or configure those parameters manually.

Once configured for PPPoE, an interface can't be assigned a static IP address.
