Ok, here is the deal. We have a Cisco VPN Concentrator, and a Cisco PIIX Firewall at our companies main link. We are a high speed broadband internet provider. At the customer's site, we have a el chepo Linksys Router that allows IPSec and PPTP pass through. We can establish a link via \\IP_Address (but not \\computer name) from one computer to another remotely and vise versa, however I cant access OTHER machines on his remote network and he cant access OTHER machines remotely either. How do I get both LANS to A) Act as one giant network or B) allow certain systems to be seen by one LAN and vise versa? This is rattling my brain!
