Is there a way to manually bind the mac address to eth0?

[snake_t]

I have a 4 port NIC for my vms, but don't know why Unraid decide to use 1 of my NIC's port as default eth0, instead of the motherboard's built-in one.

I know there's a way to change it, but as long as I change any important settings, or add/remove hardware, the eth0 goes back to the default one.

That breaks my unraid's network accessibility, and only way is to connect the monitor, mouse n keyboard to my unraid server and boot into gui mode to change it, that is a pain in the arse.

 

what if there is a way to set something to the flash's config folder, so it can prevent the problem happening again, that will be great.

Use the "Interface Rules" under network settings to assign the interfaces as you want.

yes, I can assign it by under "Interface Rules" section, but some times it reverse back to the default values.

During testing the NICs for my pfSense VM, I did encounter this problem many times, It may or may not happen (I don't have the time to test them all agian) after these changes:

• swap NIC hardware (testing the hardware)
• change the boot option (messing with nics passthrough)
• upgrade or down grade unraid (there's performance issue with pfsense, so I upgrade unraid to the next branch, but problem got worse, then I down grade back)

so I'm thinking is there a way to force assign a interface to eth0 as the "Default" default, then I don't need to change the settings in the web GUI, simply because if the eth0 go to the wrong port, I can't access the web GUI anymore.

The only way that should revert back to defaults is if you have issues with your USB Stick and it's corrupting itself, as it should be persisting your settings there.

or, the setting found some invalid configuration and reverts back.
