[vpn-help] default-route not deleted; split-tunnel

[tslbai]

Hello list,

i installed shrew-soft vpn-client 2.2.2 on Windows10 Pro 32bit an i'm
connectiong to a cisco ios-device.
Everything works fine, but the default-route to internet in my Windows
isn't deleted an so i can always use the tunnel AND the
local-internet-connection at the same time.
In Policy-tab i checked "Obtain ... or tunnel all"

I have two ways to connect to Internet.
Phone&WLAN-Tethering (NAT):
In this case it helps to uncheck the "Obtain ... or tunnel all" an set a
"remote network ressource" 0.0.0.0/0 to the tunnel.

UMTS-Stick (no NAT)
the workaround above doesn't work. The default-route to the internet
isn't deleted automatically.
In the routing-table i have two default-routes (0.0.0.0/0)
the first to the internet-provider
the second to the tunnel
... an the first matches :-(
The default-route can be deleted manually on cmd, but that's silly.

How can i avoid to have tunnel and full internet-connectivity at the
same time?

Thanks,
Florian
