Hi Derek, >From the hub to the gateway must be a trunked? On my gateway, I can see these VLAN tagged, it as if VLAN tagged traffic can go through this bridge.

So then that means BOTH sides of the linux bridge need to be Trunked as well. Unless you use the linux bridge to "untrunk" them( meaning the gateway would no longer seeing any VLAn tagged traffic) I would be posting these things to the list as there are others that may be able to answer better.

As your understanding, which one connect to trunked port? Eth0 or eth1? If both NICs all use RT8139 card, it is OK? Thanks!

If yes then you should use two e100s, one for each side.

Your meaning is, I should connect the e100 card on the bridge to the trunked port, which side? Connect to Hub or gateway? Thanks! kingz
