You shouldn't have to do anything.

Once you put an address on the wm1 interface there should be a connected
route in the routing table, and the machine should choose that route before
any other.

If it doesn't work, it could be an npf thing in which case I don't know off
hand how to solve that. I haven't spent much time with npf yet. Turning off
npf would confirm that.
