--- Comment #8 from Vitaliy Margolen vitaliy-bugzilla@kievinfo.com 2012-04-08 11:51:59 CDT --- This bug already depends on way too many things that are not implemented at all in Wine. Replacing all of those (ras, npp, etc) can't work.
When you fix those bugs then it makes sense to actually look at this bug. Which can't work either - Wine does not emulate any of the network interfaces. PPPoE requires creation of a new interface and rewriting big parts of Wine.
