TO as lan dhcp client with ipv4 & stateful ipv6?

Hi,

My Omnia is DHCP client both for IPv4 and IPv6 (Orange France ISP)
I have two interfaces ‘wan’ and ‘wan6’ on physical ‘eth1.832’ i.e. WAN connector on VLAN 832

config interface 'wan'
    option ifname 'eth1.832'
    option proto 'dhcp'
    ...

config interface 'wan6'
    option ifname 'eth1.832'
    option proto 'dhcpv6'
    ...
