WAN6 Interface won't come up

Installing and Using OpenWrt

HI All,

I've since updated to a new router. Since doing so, I've not been able to bring the WAN6 interface up. I'm sure it's something really simple, but I can't seem to see what I'm missing!

This is a readout from the CLI:

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

config interface 'wan6'
        option device 'eth1'
        option proto 'dhcpv6'
        option reqaddress 'force'
        option reqprefix 'auto'

I have restarted the router and attempted to restart the device to no joy. The system logs say:

Tue Nov 19 22:12:47 2024 daemon.notice netifd: Interface 'wan6' is now down
Tue Nov 19 22:12:47 2024 daemon.notice netifd: Interface 'wan6' is setting up now
Tue Nov 19 22:12:48 2024 daemon.warn odhcpd[1733]: No default route present, overriding ra_lifetime!

As far as I was aware, it's the same as my previous setup - however, it didn't have this issue. So, I must be missing something.

Post ubus call system board output and format all texts from system using nice </> button above.

And describe step-by-step how you "upgraded" "old router"

Hi,

{
        "kernel": "5.15.167",
        "hostname": "Router",
        "system": "ARMv8 Processor rev 4",
        "model": "ASUS TUF-AX4200",
        "board_name": "asus,tuf-ax4200",
        "rootfs_type": "squashfs",
        "release": {
                "distribution": "OpenWrt",
                "version": "23.05.5",
                "revision": "r24106-10cc5fcd00",
                "target": "mediatek/filogic",
                "description": "OpenWrt 23.05.5 r24106-10cc5fcd00"
        }

So, I got a new ASUS AX4200 and fresh installed OpenWRT and then rebuilt my VLANs from scratch. I had initially tried to just import the old config file from my WRT1900 ACS - however, it didn't like the Wireless config. So, I used this as an excuse to rebuild everything as new.
