WireGuard Lan access does not work on Linux but on Mobile phone

I'm trying to connect my Laptop (which is running fedora or manjaro) to connect all the time to my raspberry Pi with PiVPN. I have set up the IP tables and also port forwarding. I can access my Pi under 10.6.0.1 but not my normal subnet 192.168.0.0/24. On my mobile phone I can access my Local Lan from other networks, but not from my laptop. I've generated the wg0.conf wireguard file from PiVPN and put it under /etc/wireguard. And it is working. But I can't access the Lan. It should route all traffic through the Pi. I've tried adding more to the Allowed IPs but this did'nt helped either. I also added IP Tables in the conf file. Is it a problem with the OS or Wireguard? I also can ping 10.6.0.1 (PI) from another network while being connected over WireGuard, but when I try to ping 196.168.178.35 (LAN PI) it says couldn't reach host.
