Thank you for the response mpyhala. I do see the shares when I use the IP address of the server. I am on the local (main office) end of the tunnel. The same technique does not work from the remote end. I can ping the server but I do not have access to it from Windows Explorer. I believe it is a simple task that I need to do but I have never set up a VPN before.
I have at the local office: A Netopia DSL router/modem (AT&T) in full bridge mode with static IP. A Cisco RV042 (IPV4 = 192.168.1.3) with DHCP for the office. A Buffalo TS_XL Terastation (192.168.1.2) network attached storage unit holds our critical data.
I have at the remote office: A (???) cable router/modem (Cox) in full bridge mode with static IP. A Cisco RV042 (IPV4 = 192.168.2.1) with DHCP for the office. The gateway to gateway tunnel is functioning properly. At the remote office, I do not have access to the data on the Terastation. I can ping it, but it does not show up as drive in my explorer window.

I assume that the TeraStation is configured with an IP Address from you the Local Office Range 192.168.1.X / 255.255.255.0. Lets first make sure that Such Problem is Only related to the TeraStation Not a Global Problem between the 2 Sites. Can you create a Shared Folder on any Workstation / PC / Laptop on the Local Office ( 192.168.1.x ) - other that the TerStartion - and try to open this Shared folder from the Remote Office using the IP Address of the Test workstation / pc / laptop ( Example : //192.168.1.10 ). Of course, make sure that the Test workstation/pc/laptop used in the Local Office has no Firewall / AntiVirus / Security Program that might prevent the SHared Folder Access.
