TP-Link RE450 v3 wifi extender mac problem

My RE450 is connected to a router over wifi and a cable is connected to it from my physical machine running 3 virtual machines. The mac address that router sees is always the wifi mac of the RE450, not the macs from virtual machines and is then blocking packets, because the ip address is always different and the mac is the same. Router is Fritzbox 7590.
Is this at all solvable on the OpenWRT?
