Wan6 - Unknown error (DEVICE_CLAIM_FAILED)

Installing and Using OpenWrt Network and Wireless Configuration

Okay, something is very strange here. As a test, I temporarily set the protocol on WAN (eth0.2) to 'DHCPv6 client' instead of 'DHCP client' and restarted the interface. Thereafter, as expected, I pulled an IPv6 address via DHCP and could use ping6 as a test, BUT the IPv4 address was gone and I couldn't use ping4 (again, as expected). After then going back into the WAN (eth0.2) configuration and changing it back to 'DHCP client', I pull an IPv4 address on WAN and an IPv6 address on WAN6 (which is just an alias for WAN).

Now that it is working as intended, I see that my /etc/config/network file has changed to:

# cat /etc/config/network 

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

	option peerdns '0'
	list dns '2606:4700:4700::1111'
	list dns '2606:4700:4700::1001'

config switch
	option name 'switch0'
	option reset '1'
	option enable_vlan '1'

config switch_vlan
	option device 'switch0'
	option vlan '1'
	option ports '1 2 3 4 6t'

config switch_vlan
	option device 'switch0'
	option vlan '2'
	option ports '5 0t'

The only difference that I see between the two files is that the broadcast option has been disabled on the WAN interface:

Does that make sense? Again, I appreciate the advice as I'm still learning. :slight_smile:
