Maybe VLAN, did not: eth1 entered promiscuous mode

I looked in the LuCI interface and it seems all OK.

The /etc/config/network has:

config interface 'wan'
    option ifname 'eth1.101'
    option proto 'dhcp'

The /etc/config/firewall has:

config zone
    option name 'wan'
    list network 'wan'
    list network 'wan6'
    option input 'REJECT'
    option output 'ACCEPT'
    option forward 'REJECT'
    option masq '1'
    option mtu_fix '1'

config forwarding
    option src 'lan'
    option dest 'wan'
