Hello,

Ive tried for the last week to setup my networking with vlans without luck.

My setup is;

|->(trunk) to another proxmox server
Proxmox - (3 nic bond for switch with lacp (and 1seperate nic to wan)) -> Cisco SG350 switch - (trunk) -> Cisco RV260W where i use a LAN instead of WAN to make it an AP.


My VLANS are: 1,2,3 & 4
All the network gear uses untagged: 1 and tagged: 2,3 & 4
My network card is a 4lan port combo for HP Microserver Gen10+
WAN: vmbr1
LAN: vmbr0

The vmbrX´s are connected to a a OPENSense vm which runs an dhcp for the networks.

First I tried every config via vanilla Proxmox with vmbr etc without luck. I Only got the WAN and LAN VLAN: 2 to work and also wireless tagging as VLAN2.

The following in my config in OVS format - here everything works in the vlan section except WAN(?) for some reason? The only places I do set tagging is in the properties for the nic connected to the vm (i.e tag=2) - correct?

ovs_type OVSIntPort

source /etc/network/interfaces.d/*

Anyone smart enough to correct this as apperently I am not...

Why do you have mtu=1 in your vms network adapter config?
