Need help, routing

Can you please explain in detail how to do this. I have the same problem i cannot access the pc from the network.

local network 192.168.86.1
glinet 192.168.8.1
glinet pc 192.168.8.219

I would like to connect the network share from my local network. Say 192.168.86.45 ----> 192.168.8.219 share bypass the vpn for local traffic.

Thanks
