I have a Windows 7 64 bit desktop machine which is connected to a LAN.
I recently installed ShrewSoft VPN client v 2.1.7 on my machine so that I can connect to a license server hosted by my customer. They are running a Cisco VPN server and I originally tried (unsuccessfully!) to use the Cisco VPN client for Windows 64 bit but the default gateway wasn't being configured correctly after loading in my pcf file. Using ShrewSoft I am able to import the same pcf file, and successfully connect to the machine I need to using the VPN client software. The client machine I need to connect to has IP address 1.52.90.33.
The problem is that when I am connected to the customer network using the VPN client application (and after a few minutes) I lose my LAN internet connection. I can only presume that this is because, by default the ShrewSoft VPN client application automatically tunnels all traffic through the VPN connection. I know there is an option to switch off the "Tunnel All" option on the Policy tab of the application and enter a Remote Network Resource (to "Include" or "Exclude") as "Address" and "Netmask" IP addresses however I am not sure what I need to enter here.
Here is my ipconfig output before connecting to the VPN (with suffixes blanked out):

Yes, before connecting, you need to untick the "Enable DNS" in "Name resolution" tab of the Shrewsoft connection. Then, after connecting, remove the route 0.0.0.0 that points to the newly obtained ip from vpn virtual adapter. Then manually add routes to networks you want to access over vpn adapter. This procedure will enable you to use your default internet connection while conected to vpn, but you'll have to do it every time. I've made me a batch file that i run after connect which adds/removes the routes.
Windows batch file (
cmd.exe) commands:
