Network interface naming errors ?

[DrKamp]

Hello Everyone. 

I'm a brand new user to unraid and am playing with the trial version and test hardrive before setting up my final box.

I have an MSI B460M mother board with 2.5Gb realtech LAN.

I added a 4 ports HP nics via PCIe.

 

I want to setup Opensense as a VM using 2 of the ports on the quad port pcie card.

I therefore tried understanding (using this pretty complete forum here) how this works.

After several trial and errors (including having to shutdown > delete config/network.cfg > start) I came upon this which puzzles me. 
Could you please explain to me if this is normal and me juste beeing ignorant, or if there's something actually problematic ?

 

In settings > network, I see the following sections and values (trunkated for readability)

Interface  eth0

MAC : 2C:F0:5D:AE:55:20

Bonding: Yes (active-backup) with members : eth0,1,2 and 3

Bridging: Yes

Config : Ipv4 - DHCP

 

interface eth1 (same config for eth2 - eth3)

Member of bond0 (see eth0)

MAC : 2C:F0:5D:AE:55:20 (same as eth0)

 

Interface eth4

 

MAC : AC:16:2D:9C:32:6B

Bonding : No

Bridging : yes

 

And then next section is : Interface Rules

 

Interface eth0: 2C:F0:5D:AE:55:20      PCI device 0x10ec:0x8125 (r8169)

Interface eth1:  AC:16:2D:9C:32:68      PCI device 0x8086:0x150e (igb)

Interface eth2: AC:16:2D:9C:32:69      PCI device 0x8086:0x150e (igb)

Interface eth3: AC:16:2D:9C:32:6A      PCI device 0x8086:0x150e (igb)

Interface eth4: AC:16:2D:9C:32:6B     PCI device 0x8086:0x150e (igb)

 

Question :

I don't understand how on the first page of the page, the eth0 as mac adress different  from the the last section...

Do eth0 - 1 - 2 - 3 - 4  refere to logical network interface (if terminology is correct) i mean ports or do they refere to some logical naming of the ports ?

Also, How can i change my config to access the webGUI via the 2.5Gb port (mac is 2C:F0...) and be able to also "isolate" my other physical ports so that I can pass them to VMs. (I don't necesseraly need passethrough unless it's required for security reasons or any other good reason.

 

THanks a lot and have a good day.

 

PS : (EDIT) - anytime I try to set turn off bonding on eth0, I loose connection to the server... (explaning the need to delete the usb network config file). I can't understand why....

If you want to use the NICs for different things you must disable bonding, and it will show the MAC for each one.

Thanks. 

I went with the Bridging to a BRx network for 2 of those nics. 
I used those 2 BRx networks in my VM config.

Seems to work pretty well.

It might not be th ebest solution in terms of security... But it's a problem for later...
