 Wow, thanks so much!  I will take a look and give it a try.  Thanks Stefan!

 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.
