v7.2.3

Eth0 (onboard) was used for the life of the server. Installed a 10gig NIC and now Eth2 is in use.

cat /boot/config/network.cfg and it looks like this:

# Generated settings:

IFNAME[0]="eth2"

DHCP_KEEPRESOLV="yes"

DHCP6_KEEPRESOLV="no"

DESCRIPTION[0]="Gig-Eth2"

PROTOCOL[0]="ipv4"

USE_DHCP[0]="no"

IPADDR[0]="192.168.0.5"

NETMASK[0]="255.255.255.0"

GATEWAY[0]="192.168.0.1"

METRIC[0]="9"

VLANS[0]="1"

SYSNICS="1"

I tried adding dns manually to the file and it won't stick. There is nowhere in the GUI to add dns to eth2, just eth0, and I've tried various configs and dns will simply not work.

How can I tell unraid that eth2 is the new (and only) NIC, and where can I configure dns? This change has broken all sorts of things, including the function of all docker web guis.

DNS settings are/can only be applied to ETH0.

That's not a bug because DNS works above routing and therefor is global to all NICs.

If you want to make the 10G card your main nic, define network rules and rename it there to eth0.

(you can switch the MAC addresses with the drop boxes)
