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):
