As some of you may recognize... I've been trying to get VLANs working on ProxMox for well over a year. They worked with straight Linux, but never in ProxMox. I left the project and tried a few other OpenVZ managers. Never got them to work with VLANs either.
Finally, I just gave up and plugged a second network cord in and just move the public Internet over 1 NIC and the internal network over the other NIC.
