interface configuration

[maesdamian]

Hello

I just upload a proxmox server, I'm totally new in this and in linux, I got stuck and out of fear I do not move forward, the query is this

From a proxmox server, I have "x" virtual machines of which I want to have private and public ip (the public ones I already have them ready to put), currently if I have a private network, but I do not know how to add the other interface if it is the case , what I think is serious, if someone corrects me in good time


auto lo
iface lo inet loopback
iface eno1 inet manual
+iface eno2 inet manual

+iface eno3 inet manual

+iface eno4 inet manual

auto vmbr0
iface vmbr0 inet static

In general it could look OK, hard to tell for sure as one would need to know the exact interfaces (ip addr) and which physical interface should be private and which one public.

should the private network be for node (server) internal use only? Then this is OK:

bridge_ports none

Else, if you have a separate network switch for your private network you need to specify the respective physical interface here, e.g. eno2

Then just add an additional network interface to each virtual machine with vmbr1 as respective bridge.
