I can't seem to find out how to add it back. I've added a metric of 1 to the gateway in the NIC settings. Rebooting and disabling/re-enabling the bridge doesn't bring it back.  I added a NIC and under network settings changed my old nic to ETH1 and new nic to ETH0, I'm wanting the new 2.5gb ETH0 NIC to handle all functionality, I also noticed under "Interface Extras" that it only shows br0, eth1, and tailscale1, but not eth0. Is that a problem? If so, I'm not seeing a way to add it back.

Reset your unraid network config and start over.

Make a backup. Main > Flash > Flash Backup.

Example:

root@BMM-Unraid:~# cd /boot/config
root@BMM-Unraid:/boot/config# ls
Basic.key          domain.cfg  go         iscsi/             parity-checks.log  pools/       shares/            ssh/       vfio-pci.cfg
avahi-daemon.conf  drift       go~        machine-id         passwd             random-seed  smb-extra.conf     ssl/       wireguard/
disk.cfg           editor.cfg  history/   modprobe.d/        plugins/           secrets.tdb  smb-override.conf  super.dat
disk.old           flash.cfg   hosts      network-extra.cfg  plugins-error/     shadow       smb.conf           super.old
docker.cfg         forcesync   ident.cfg  network.cfg        plugins-removed/   share.cfg    smbpasswd          udev/
root@BMM-Unraid:/boot/config# 

In my case if i want unraid to remake the network configuration we need to remove the 2 network config files.

 

mkdir /boot/config/backup
cp /boot/config/network*.cfg /boot/config/backup/
rm /boot/config/network*.cfg

 

then reboot unraid. Check a monitor/console for its IP it got over dhcp...

this will bring you back to factory default unriad config for networking.
