VPN: Forticlient SSL VPN and FRITZ!Box 7490

[Riccardo]

Hello,

I have a need to connect from home to my corporate server through VPN (there do not use the FRITZ! Box). I use FortiClient SSLVPN (version 4.0.2287) on Mac OS X 10.7.5 and FortiClient SSLVPN 4.0.2291 on Windows XP.

At home I use a modem / router FRITZ! Box 7490.

The VPN connection is established but when I try to access to network resources I get the following error message:

There was an error connecting to the server "192.168.1.15" The server may not exist or may not be available at this time. Check the name or IP address of the server, the network connection, then try again.

I did a test using the 3G network from my smartphone (used as hotspot, then avoiding using the router FRITZ!Box), the VPN connects and I can access to network resources. Also some of my colleagues who have a classic modem from home don't encounter this problem, using the same version of FortiClient SSLVPN.

Is there any configuration I can do to your router? How can I fix?

Thanks a lot!
