No connect to french OVH "collecte VDSL"

Has someone successed to connectan openwrt modem to OVH VDSL2 (collect by orange...) ?

Thanks for any help in parametring.

Beginner in openwrt...

openwrt doesn't do a lot of modems, who's the manufacturer ?

I did not think it matters but I use a Netgear DM200....

Personne n'utilise un modem openwrt avec OVH....?
