I have a problem connecting to our VPN with a new Windows 7 notebook, but only if I'm connected to internet via my mobile-provider (internet connection works, Firewall on/off same error). If I'm online via my home-lan, vpn-connection works. With the old Windows XP notebook, connected via mobile-provider, the vpn works also, so I think it's not a problem of the vpn-settings on our router.
I get the error 0x800B0109 (see screenshot also), google-research did not find a solution for me.
Anyone knows what could be the problem?
Thank you for helping,
