Help Configuring Both Ethernet Ports as WAN on VisionFive 2 Board in OpenWRT

Hi,
I am trying to configure both Ethernet ports on the VisionFive 2 board as WAN ports. By default, OpenWRT sets Eth0 as a LAN port and Eth1 as a WAN port. I modified the config file (shown below) to assign both ports as WAN, but I am unable to get Eth0 to work properly. Could you please help me figure out what I might be missing?

Here is my /etc/config/network file:

config interface 'loopback'
    option device 'lo'
    option proto 'static'
    option ipaddr '127.0.0.1'
    option netmask '255.0.0.0'

config globals 'globals'
    option ula_prefix 'fd10:ebc0:67a2::/48'

config interface 'wan'
    option device 'eth0'
    option proto 'dhcp'

config interface 'wan2'
    option device 'eth1'
    option proto 'dhcp'

Thanks in advance for your help!
