want to use both my 2 nic cards on my server

[fh84]

hi there..

im a noob when it comes to proxmox.. need help

i have a server node which has 2 ethernet ports

how do i use the second ethernet port ? (please check the screenshot.. i want to be able to use eno2)

i wish to setup something like pfsense where i need to be able to use both the ethernet ports

i only have an unmanaged switch.

the simplest way is to create a new vmbr1 and link it to eno2 - then you create a VM for pfSense with two network interfaces - 1 on vmbr0 (which will be your LAN interface) and 1 on vmbr1 (this will be the WAN interface)

see here

thank u so much bobmc!!

now my issue is ... the lan interface is shared with proxmox and pfsense lan... would it cause any issues ??

is it a better idea to have separate lan and wan from the proxmox mgmt interface ??

also... why does the vmbr0 have an IP assigned to it ?? shouldn't the IP be assigned on the VM using that vmbr0 bridge ?? i know its the proxmox mgmt IP but do i have to assign it there ?

its common for vmbr0 to be shared with proxmox (as a management interface) and some or all of the VM's running on the host. This is the default setup when proxmox is installed. Multiple other scenarios are possible but the default setup is perfectly fine as it is.

If you have two ethernet interfaces and you want to install a firewall/router such as pfSense, then it's recommended to have seperate LAN and WAN interfaces and to dedicate the WAN interface to pfSense only.

Proxmox needs a management IP, this being on vmbr0 doesn't affect the VM's which can have their own IP on vmbr0 at the same time - it's best to think of vmbr0 as being like a network switch, many systems can be connected to it, all at the same time.

You will need to think about how your network will operate once pfSense is installed. I notice that your gateway is currently 192.168.1.1 which I would assume is your internet providers modem/wifi box. The usual setup is that pfSense becomes the default gateway - at least for your VM's - but what is your plan?
