Wireguard VPN can't access LAN devices

[Pedroa]

Hi!!
I'm trying to set up a VPN using Wireguard, but it's impossible to me to make it works 100% ok.
I tried to setup Wireguard VPN on 25 version and recently on 26.1.9 and It's impossible for me to communicate with the other network devices.
I set up, interface, assignements...
I verified firewall rules and normalization, peers configuration...
I followed one hundred of tutorials! 
My laptop connects ok using Wireguard client. I see traffic in the client and in Opnsense\VPN\Wireguard\Status\laptop-peer. I can ping firewall ip and I've Internet connection but I can't ping my Windows server or another pc that are connected at LAN.
Need help. Please!!
