[PVE-User] Adding an Internet NIC to existing Proxmox

Sun Feb 28 20:36:33 CET 2021

 I just purchased a Netgear 48 Port GS348T that will do VLANS.
Let's say I want to "trunk" VLAN 20/30 over to port 48 of the Netgear 48 Port switch, I would run a patch cord from what interface (NIC) below to port 48.  Then the (8) VOIP phones I need to do would need to trunk VLAN30 (VOIP) and VLAN20 (Computer) on say ports 1-8 and then I would just set the other ports for VLAN20 only just for VLAN20?
I am sorry to get so complicated but this is what I want to do and of course try and understand what I am doing as I do it.  I really appreciate all of your help.
I apologize for taking so long to get back to you, I am going to try and understand what you have shown me.

This is pretty much way over my head but I am trying to understand.
I have (6) Nic ports that I am using presently.  I have lost track of which NICs that I am using for what.  I come from the simple world of ETH0, ETH1, ETH3 and so on.
(1) Internet(2) 192.168.20.0/23(3) 192.168.30.0/24
Since you have shown me how to have an Internet NIC and then the two local Nets, my install is geting much more complicated.
I have added pfsense and wireguard into the mix throwing addition interfaces into the mix I assume, I will lay them out here:

 Here you go.
See interface enp9s0f0 in the config below.It also shows how to run tagged (vmbr20,vmbr30) and untagged (vmbr10) traffic on the same trunk interface.
I normally use the VLAN tag ID as the bridge identifier (e.g. vmbr20 and vmbr30).The host IP would typically be on vmbr0 and thus on the native (untagged) VLAN.

Tried it and it worked as you explained!  Thanks Stefan.  I am taking this step by step.I haven't tried the 192.168.30.0 nic yet but will shortly.
I will want to be able to trunk VLAN 20 and VLAN 30 down a NIC so that I will be able to use my VOIP phones on VLAN30 and be able to offer VLAN20 for the attached work stations, any suggestions and/or configuration file to do this?
Thanks again for your help!

Hi Steve
Attached and below is an /etc/network/interfaces that should do what you want.
Just* keep interface enp9s0f1 connected to your private subnet 192.168.20.2/23* connect interface enp9s0f0 to your internet subnet* connect internet VMs to vmbr1* connect interface enp11s0f1 to your private subnet 192.168.30.2/23* connect VMs on subnet 192.168.30.2/23 to vmbr2 If you keep the comment lines (#) they'll show up in the web interface as well.
Disclaimer: I did not test it but it should give you the right idea to go ahead.

I need some help.  I am new to Proxmox.   I have it set up now using (1) one NIC to an internal network of 192.168.20.0/23 and I would like to use another NIC I have available for the internet which has (5) available IPs.
I have attached a view of my existing network.
I would like to set up an additional (NIC) when would allow me to assign to a virtual server that has two virtual NICs with one being the internet and the other being my internal network.
While I am at it, I have another networking 192.168.30.0/24 that I would like to assign to an available NIC so that I could assign virtual servers to that NICat a later time.
Could someone please help me on how to do this
Thanks very much.
