Hi there... thanks for the feedback...


I was actually hoping to use split-tunnel and thought that below had
configured it... obviously not...:)  The users who are coming in remote are
also people who work in the office during normal hours.. this VPN is for after
hours work basically so I don't see as much security concern (but I do
understand your concern)...

Thanks,

Paul
