I have a VPN set up box to box using Netgear VPN routers.  If I turn off the windows fire wall on the windows 7 machine, I can access shared printers and files.  But, when I turn on the firewall, it blocks access, and even stops responding to pings.  The computers that are on the same side of the VPN as the Windows 7 machine access shares just fine.  What exeptions do I need to make in the firewall to allow traffic from across the VPN Tunel?

Try filtering TCP ports from 135 through 139 which are used for file sharing and printing .

Hope it helps

That did not seem to work.  I don't get a message that says that it is blocked.  It does not respond at all until I disable the firewall.

OK. I found the answer by myself.

Go to "Windows Firewall with Advanced Security" in "Administrator Tools".

Select "Inbound Rules"

Find "File and Printer Sharing (SMB-In)" Local Port 445. There are several these rules. Select the active one which has the green button. The default setting for "Remote Address" is "Local subset". Change the "Remote Address" to "Any". It works.
