Problems with multiwan and unbound

[Fever_Wits]

Hello,
i have 2 internet providers. I have made a balance between the two internet providers.
I used this documentation: https://wiki.opnsense.org/manual/how-tos/multiwan.html
But I have a problem with unbound.
If I make point 4, unbound does not work. All who are behind opnsense have no resolv.
If i remove it unbound works, but i have no balancing of traffic.

Did anyone have a similar problem or idea what is happening.
