Abstract
A communications system and method for dynamically creating at least one pinhole in a firewall are provided. The communications system includes a protected node capable of initiating a communication session with an outside node. In this regard, the protected node is capable of receiving flow parameters regarding the communication session as the communication session is setup. The system also includes a firewall disposed along a communications path between the protected node and the outside node. The protected node is capable of sending at least a portion of the flow parameters to a firewall-controlled proxy, which in turn, is capable of forwarding the portion of the flow parameters to the firewall. Thereafter, the firewall is capable of creating at least one pinhole based upon the portion of the flow parameters to thereby permit the transmission of information between the outside node and the protected node during the communication session.
