I am trying to configure an A/S firewall cluster, and I have the interface configured as a PPPoE client. When I try to configure the clustering on ASDM, I get a message saying that high availability is not possible with a named interface configured as a PPPoE or DHCP client.
Why they does it say named? I know naming an interface is not optional in a Cisco ASA. If anyone has advice related to clustering with this way, please share it.
