A system for providing connectivity to employer networks for support personnel and consultants who regularly work at customer locations. A secure network mechanism is provided to connect these users at the customer locations with their respective employer networks for the purpose of accessing e-mail, reference material, specialized application databases at their company, etc. Multiple VPNs are provided for the transmission within a customer location and for transmission to the employer servers to maintain security and control at the customer location and across the Internet connection. The customer location may inspect data and control what leaves their facility, while the consultant employer network is allowed to control user access to their own network. Name server information is also transferred between the disparate networks so that a consultant looking for a common server name in his own employer network gets the correct connection instead of the local customer's server connection.
