I dont think so. This is directly out of the Online Help in the Astaro Interface.
DSL (PPPoE): PPP over Ethernet. A DSL PPPoE device lets you attach your firewall to "PPP-over-Ethernet" compatible DSL lines. These devices require a dedicated Ethernet connection (they cannot co-exist with other interfaces on the same hardware). You must attach a "DSL modem" to the interfaces network segment. The network parameters for this device types can be assigned by the remote station (typically, your ISP). In addition, you need to enter username and password for your ISP account.
