How to Add a Second Ethernet Port to your Proxmox Server

In this video, we'll show you how to add a second Ethernet port to your Proxmox Server. This will allow you to connect additional devices to your server without having to re-install the operating system and you can assign another network to it etc (vlan).

If you're struggling to find a way to add more devices to your Proxmox Server, then this video is for you! We'll show you how to add a second Ethernet port to your server in just a few easy steps, allowing you to add more ip's without any hassle!

you shouldn't need to power anything down. these usb dongles are usb plug and play and so long as the drivers are in the active environment (they usually are), you just need to plug it in, plug in some ethernet, refresh the web ui, and add the network adapter to your network interfaces section of proxmox.

Could recognize those monoprice Ethernet cables anywhere, great setup!

With those tiny PCs I'd recommend getting a tiny m.2 to Ethernet adapter that fits in the empty port on the back. Usb to Ethernet works great, but costs performance, since it has to go through the CPU.

Great. I would use that second port for migration / replication traffic. Datacenter --> options --> migration. It will set an IP directly to the physical NIC. So there isn't a bridge.

NIce little stack there man !! DAMN !!

I did this set them as a bond to get a bit more speed out to my network.

What’s some interesting use cases for an extra Ethernet port? Thanks for the vids

[Anuituu]

Between Dell Optiplex Micro, HP Prodesk, HP EliteDesk and Lenovo Tiny, between that and all of their variant, which is more power efficient using Proxmox?
My goal is far below 35KWh, since that is my benchmark from 2nd and 6th Gen Intel T processor.

I tried this, but after a reboot of Proxmox the adapter get every time a new name ... -.-

What I did on my proxmox setup was add a second gigabit ethernet and ran the Wan connection on it. Then I used the internal network connection to my network switch. That was even if I lose internet connection or the usb network fails the internal network still remains and I can access my network and VM's.

I have no idea about any of this, but I want to learn yet I don't have the money to do it.

[redone]

Would you share what this is used for? Is this for redundancy, to increase bandwidth or both? Thanks.

[dazealex]

Which particular USB Ethernet is that? I have from Unpluggable and it isn't recognized (it is, but gives me a config error when I pass it to my VM), I'll try creating a bridge instead -- maybe that'll work.

[KevinGDoP]

name of that rj45 connector, translucid

[milandzuris]

Whats the Brand of this ethernet cables? Thx

[Josef-K]

Those fail after about a month but why do I need two when I have virtualization?

[curtispavlovec]

Bad idea as the USB are all junk Realtek chips and unstable and unreliable for real networking (pfSense et Al).

[sabarinaths]

I don't have a working ethernet port in my motherboard, can i use a USB to ethernet port for proxmox ?

[RetroComputingwithMike]

Don't do that, purchase a switch that supports vlan instead, that's a much cleaner setup and gives you way better performance.

dude, usb to ethernet on a server ?!?!?!... sacrilege !
