Is there a mismatch between your VPN server and your endusers configuration?
If the Windows machine use "send all traffic through VPN", then openswan
needs a rightsubnet=" option.

So this seems to suggest you do not tunnel all traffic through the VPN, so
you will need to have your users unselect "send all traffic over VPN".
It is somewhere in the advacned tab of the VPN's TCP/IP properties page.
