Hello, i am new to proxmox and i red a lot, maybe to much My state: I have just one node hosted at OVH. This node has a public ip und several VMs with public IPs condfigured out of the box via bridged networking. VM for web, sql, mail, etc. My first goal is to ad a VLAN, that all VMs can talk to each other over a private network to make it more secure. But i am not able to do it for myself at this point :/ Here is my node config. cat /etc/network/interfaces: Code: auto lo iface lo inet loopback iface eth0 inet manual iface eth1 inet manual auto vmbr1 iface vmbr1 inet manual bridge_ports dummy0 bridge_stp off bridge_fd 0 auto vmbr0 iface vmbr0 inet static address XXX.XXX.XXX.XXX/24 gateway XXX.XXX.XXX.254 bridge_ports eth0 bridge_stp off bridge_fd 0 Here is a config of a VM. cat /etc/systemd/network/eth0.network: Code: [Match] Name = eth0 [Network] Description = Interface eth0 autoconfigured by PVE Address = YYY.YYY.YYY.YYY/32 Gateway = YYY.YYY.YYY.254 DHCP = none [Route] Destination = YYY.YYY.YYY.YYY/32 Scope = link NODE: What do i have to change or create in the gui to create a vlan successful? VM: What do i have to change or create in the gui to create a vlan successful?
