PPTP server on Fortigate, i can connect but cant reach internal network

SO, i have configured PPTP on FortiGate 30E, i successfully connect to server from my house but can not reach to internal network and devices behind FortiGate.

Server gives me IP that i configured and that is it, Neither internet nor internal network are reachable

can anyone explain to me what is going on?

I created users and group, enabled in CLI and gave sip and eip, created address in same range, configured policy and can connect to server. nothing else

CLI: config vpn pptp
set status enable
set ip-mode range
set eip 192.168.3.240
set sip 192.168.3.100
set usrgrp TEST
end
