Firepower 2110 PPPOE

Firepower 2110 only has interface type static and dhcp.I cannot see pppoe option in WAN interface.

I use FDM for management.

As noted below, FDM-managed Firepower Threat Defense hardware appliances added PPoE support in 6.6.

PPPoE is not supported on FMC-managed devices. If your ISP requires PPPoE, you will have to put a router with PPPoE support between the FTD and the WAN modem (when using FMC management).

Then I have only two methods now.

1.put a router with PPPoE support between the FTD and the WAN modem.
2. Can it be achieved by downgrading the version?

@sxzhang23300

PPPOE was introduced in FDM from version 6.6

Thanks for the update @Rob Ingram. I had forgotten they added that to FDM only in 6.6.

I corrected my earlier reply.

When you configure/edit the physical interface, for IPv4 for example, under IPv4 choose "PPPoE" and you should see the authentication parameters, see attached:
