You can avoid Linux with this approach and careful selection, but then you're probably running VxWorks instead. But at least this way your other OS is little more than a media converter, only the OpenBSD box needs to deal with externally sourced IP traffic.. Most ADSL "modems" can bridge ADSL to Ethernet which is fine for PPPoE ISPs or those doing IP directly (fairly rare) but they won't usually work with PPPoA-only ISPs, exception being the couple of Draytek models that 'translate' PPPoA to PPPoE, and some old speedtouch boxes do the same to PPTP. But for most ISPs that's not needed and a normal bridge is enough. > On Tue, Dec 22, 2015 at 07:32:57PM +0000, Frank White wrote: >> Hi, >> Yes I am sorry, I want build a small embedded system with openbsd to >> connect a lan to an adsl line.

Doing this strictly OpenBSD-only is going to be a _lot_ of work unless you find a ueagle(4) device from a museum and run an ancient OpenBSD release from before the driver and subsystem was removed.
