           Summary: Please consider adding possibility to have multiple
                    PPPoE sessions with different MAC addresses
    Kernel Version: 2.6.current, 2.4.current
            Status: NEW
          Severity: low
             Owner: acme@conectiva.com.br
         Submitter: mh+kernel-bugzilla@zugschlus.de


This wishlist item is mostly relevant to German users. In 
Germany, Deutsche Telekom has a near monopoly regarding DSL 
connections to residential homes. They are, however, required, to 
resell their network to other ISPs which has led to a rather 
interesting combination of Internet tariffs and feature sets available 
via Deutsche Telekom T-DSL connections. 
 
Technical Basis for the T-DSL customer interface is PPPoE over a 
bridged ATM session, so it is technically possible to have multiple 
PPPoE sessions on the same line, allowing concurrent use of more than 
a single ISP which might be interesting with special interest services 
like streaming, fixed IP address and/or flat rate. 
 
However, Deutsche Telekom technically forbids multiple PPPoE sessions 
originating from a single MAC address, so one needs multiple network 
interfaces to originate the PPPoE sessions from. 
 
Sven Geggus has a patch against rp-pppoed, which allows to fake the 
sending MAC address for additional PPPoE sessions, circumventing the 
artificially introduced limitation of the T-DSL connection. The patch 
is available on http://geggus.net/sven/rp-pppoe-fakemac.diff 
 
Please consider adding that possibility to the kernel PPPoE code as well. 
 
Greetings 
Marc

[Nguyen Dinh Nam]

I have another situation - there are 2 different PPPoE access 
concentrators available on 1 interface. So I want to be able to specify 
the MAC address (or AC Name, or Service Name) of the AC to connect to
Thanks

Does that patch help at all?
Seems to me all it enables is session setup, but after that what
happens? Do packets go out with the MAC address you just spoofed
for the data as well?

cheers,
jamal

It helps with the user space pppoed, yes.

With user space pppoed, yes. When applied to the normal pppd, using
kernel pppoe, only session setup goes out with the fake MAC, and this
doesn't lead to a useable pppoe session, of course.

Remind me again: With user space pppoe if you have a web server that
people access from outside world, all packets go to user space and then
back to the kernel before hitting user space again? Only in such a case
can i see this working ...

jamal

Yes, that's why it is called user space pppoed.
