Hi.
I have bridge with wlan and ether interfaces.
PPPoE server is runing on bridge.

PPPoE clients disconnected when interface state going down

There is disable-running-check option for wlan, but for ethernet it is absent.

How can I fix this problem?

RouterBOARD does not have disable-running check for Ethernet ports, it works automatically.
Running state is removed, if cable is disconnected.

Ok. But how can I fix disconnection problem?

have you set Admin MAC for the bridge? probably the problem is because MAC address changes when port flaps...

Chupaka GURU!

Work beter, but sometims disconnect.
