Debian 11 with birdc and Mikrotik to route IPv4 and IPv6 public IPs, routing issue URGENT

I need urgent... from now to one hour.... I has working a birdc in Debian 11 with my IPv4 and IPv6 public IPs, in this Debian my upstream announce my IPs... I have a wireguard tunnel to my home and I can assign IPv4 and IPv6 to VM and CT and computers but I have an routing issue... the Mikrotik has behind a NAT and the public IP is not my public IP... the Mikrotik public IP is my fiber line IP (in IPv4)... in IPv6 it´s right... is the public IP... I need URGENT to fix now this issue.... I think it´s a small mistake when I configure the Mikrotik... but I can´t find what.
