That depends on if Luca really wants to do that. Then again he may not. I think we should let him decide if this thread is closed. > <snip> > These routers are designed to be no brainers for windows users, yet > there are no windows drivers, therefore it uses conventional networking.

PPPoE is PPP over > ethernet, over ATM: an extra layer that is not needed. Read RFC 1661, RFC 2516 and RFC 2364 iirc. PPP, ethernet and ATM are all layer 2 of the OSI Seven Layer model. IP is in layer 3. ATM and ethernet are data links which tunnel the PPP data. PPP does the authenication and various other thing just like with dial up modems. It's not a case of tunneled PPP in ethernet in ATM. The ADSL modem deals with changing the wrapper to tunnel PPP from ethernet to ATM. ATM deal with getting the PPP data from my ADSL modem to the DSLAMs at the exchange. Ethernet deals with getting the PPP data from my OpenBSD box to my ADSL modem. I seriously doubt my exchange would understand me firing ethernet data at it or maybe I'm wasting bytes in my segments in unnecessary overheads. I'll admit this is not a normal setup but as far as I know OpenBSD doesn't have PPPoA support directly in the kernel, and I can't see why it would since most ADSL PCI cards are primaryly driven by software usually in the form of BLOBs. Maybe you fancy reverse engineering some of these cards and get them working in OpenBSD. Dan
