Abstract
A method and apparatus for facilitating communication between client computers is provided. The method provides for the use of ping probing by a server to determine the types of NAT devices and/or firewalls protecting the client computers. Once these are determined, the server can predict the response to communications from the client computers and instruct the client computers to contact each other. Once a session or tunnel is established it can be maintained through the use of a flag, even if contact with the server is lost.
