VLANs won't work

Hello, my 2 cents.
at the end i make this : all vlan tagged ( include vlan 1) ----> it's work. but i have a switch that support vlan 1 tagging.
Thank you, finally I've done what you and also udo told me, and put VLAN 1 as tagged one - ALL IS WORKING NOW!

BTW any switch that "understand" VLANs can do VLAN 1 as tagged. At least I havn't seen any that can't.

Thank you guys for helping me!
 
I am lucky then. But now I'm aware of that, thank you!

Anyway, the solution suggested helped 100%, the only downside is that I can't setup proxmox that way from GUI (so visiting 'network setup' GUI page and pushing 'save' there will destroy network setup), hope sometime in 2.x that will be fixed or improved.

Thank you for the advices!
