Fortigate 40c VPN no local LAN access

Hi everybody,

i just set up an vpn connection via forticlient on mac clients. the connection is established and i can use the servers i need behind the fortigate.

but i can´t use local lan services like printers. so i searched the fortigate for something like "let vpn users access local lan" but can´t find anything. my LAN is for example 10.1.2.x and the lan behind the fortigate is 192.168.1.x.

Did i have to make a firewall rule or something, that i can access my local lan after connecting with forticlient ?
