Network Interface only for internal RDP

[ProxHex01]

Hello,

I would like to create a network interface for a specific VM under Windows 11 to be able to access it in RDP but this VM must not have access to the internet.
I found that if a create a Linux Bridge without IPv4 and IPv6 address it should work (and put a static IP in the VM), maybe I've made a mistake but it's not working for me.

How do you guys do this?

Thanks in advance.

do not set gateway ip neither dns ip then VM can't go outside.

or enable Proxmox Firewall at datacenter and at VM level + VM NIC level. then rules to only allow rdp.

I've put nothing in the settings:



In my VM:



Do I have to edit the : /etc/network/interfaces file?

ip only in VM is correct.

No need to create another bridge.

Earlier or later you will notice weird malfunctions and have no idea where that comes from.

To avoid that do not use assigned addresses. There are literally millions of IP-addresses you can use without conflicts. See RFC1918 and/or TEST-NET-1/2/3.
