Strange Routing with FortiClient

Hello,

i have a strange problem when connected to our Company's VPN with the Fortinet Client (Mac):

-I can access all remote network devices

-I can access all my local network devices EXCEPT my local gateway/router (10.0.0.1).

netstat shows:

Destination        Gateway            Flags        Netif Expire

default            10.0.0.1           UGSc           en0       

so it's using the right local gateway. On the company's FGT "split Network" is enabled.

and now the complete confusion: If i connect to vpn via os x native built-in Cisco Ipsec all is working, i can reach my router without problems.

So, does anyone can help me out?
