create a VLAN without having a physical switch or changing anything in the router

[moshe.aa]

Hi,
I want to create a VLAN in my Proxmox,
I have a router provided by my ISP and all of it's ports are used, one of them is connected to my Proxmox server.
By checking my ISP router, it's seems like id doesn't support managing VLAN's.
The goal is to have my VMs and LXC containers on their own VLAN so they are not affected by the router’s DHCP, and so I don’t need to assign static IPs inside the router’s range.

How can I achieve that ?

Hi moshe, you have 2 options here, you enable vlan support on the first (default) bridge vmbr0. it you will put vm's on vlan 1, they will be able to communicate with router, vlan1 is the default vlan in most (all) netwerk equiptment.
If you put any other vlan besides 1, they can only communicate with other machines on that vlan.

another option,if you only have 1 PVE machine is to make a 2nd bridge device with no hardware network adapters linked, you can use that bridge to create a network that stays within that PVE host.
