Thank to Charvel.

OK now my PPPoE come back to work. It needs to set VPI/VCI exactally same as ISP is required. Also my inside home loopback is now working. The last firmware makes it works.

I updated to lastest firmware and then PPPoE is not working. I down grade to original firmware also PPPoE is not working. :( I start to hate this unit.
