Fortigate PPTP default gateway configuration

[ricec0rn]

Hi guys,

I have a fortigate 40C running with a PPTP configuration. My VPN works partly. I can connect to the office network, however I can't get the default gateway working. Can anyone help me with figuring out whats wrong with this configuration, please?
