I'm trying to configure my debian testing router using Network Manager
(in replacement of the /etc/network/interfaces file). But I've found an
issue. I can't set two connections at the same time on the same network

I've configured two connections : a pppoe and a 802-3-ethernet one. They
have to work at the same time on the same interface. The ethernet
connection is to set a local ip address for me to have access to my adsl
modem web interface. The pppoe is to setup my internet connection.

Using ifupdown, it works well. Both connections are up without any
problem. But Network Manager doesn't allow it. I've bound the 2
connections used by network manager using the 802-3-ethernet.mac-address

But when I set a connection up, the other one is disconnected. I can
only have one at a time.

Is this normal or is there a way to bypass this behavior ?

At the moment this is expected behavior, and it's a bug in
NetworkManager that has a long history and hasn't yet been fixed.  So
unfortunately NM can't meet your needs at this time.  Fixing this issue
has always been in my mind at least, and we've made slow progress
towards it, but there's still a bunch of stuff to do before it's finally

Thanks for your answer. Do you have an idea of when it could be fixed ?
It is the same bug that makes it impossible to start 2 openvpn
connections at the same time ?

That's a different and second issue :)  I'm hoping we'll fix the two VPN
thing in the next few months.  I'm not sure about when the PPPoE issue
will be fixed yet.
