single nic to multiple bridges

[antonio_ciaccia]

Good morning, everyone,
I premise that I am a novice as far as this proxmox is concerned (and maybe also as far as the network is concerned).
I am trying to configure my proxmox in this way:
- each ct should have its own network (10.10.1.0/24)
- each vm should have its own network (10.10.2.0/24)

The problem? I only have one NIC.

This currently my configuration!

auto lo
iface lo inet loopback

iface enp0s31f6 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.188.51/24
        gateway 192.168.188.1
        bridge-ports enp0s31f6
        bridge-stp off
        bridge-fd 0


source /etc/network/interfaces.d/*

I thank in advance anyone who can help me out!
Thank you very much

Hi,
you can separate the networks based on VLANs, I recommend having a look at the SDN features introduced with the latest Proxmox VE release. See https://pve.proxmox.com/pve-docs/pve-admin-guide.html#chapter_pvesdn, especially the section about network zones https://pve.proxmox.com/pve-docs/pve-admin-guide.html#pvesdn_config_zone

Hi, and thank you very much for your reply Chris.
In the meantime, I tried configuring like this.
Can anyone be able to give me feedback?

Do you require the Proxmox VE host to have VLAN tagging as well? Otherwise you could better achieve the network separation by setting vmbr0 to be vlan-aware and only tag the VMs/CTs NICs with the required VLAN tag. Also, you can find some configuration examples in this wiki article https://pve.proxmox.com/wiki/Network_Configuration#sysadmin_network_vlan

No, absolutely no need for the host to have a VLAN tag. I tried to execute trying to adapt the examples to my use case, but with poor results.

I also tried running several online guides, but even those did not get me the desired result.

My goal is to use my one NIC to access Proxmox VE via this address 192.168.188.51/24.

While all the VMs will have to have (10.10.1.0/24) and the CTs (10.10.2.0/24) so as to isolate them.

Thanks
