1. A method for communication between two or more endpoints, said method comprising:

  • receiving, at a first intermediate communication device that is communicatively coupled with a first endpoint communication device, a plurality of multiport packets of data in a multiport communication protocol for communication from the first endpoint communication device;

    converting, by said first intermediate communication device, said plurality of multiport packets into a plurality of single-port packets in a single-port communication protocol;

    transmitting from said first intermediate communication device said plurality of single-port packets over a commonly-open port to at least a second intermediate communication device that is communicatively coupled with one or more other endpoint communication devices, said plurality of single-port packets traversing one or more firewalls using said commonly-open port;

    receiving said plurality of single-port packets at said at least a second intermediate communication device;

    reconverting, by said at least a second intermediate communication device, said received plurality of single-port packets into said multiport communication protocol resulting in reconverted plurality of multiport packets; and

    delivering, from said at least a second intermediate communication device to said one or more other endpoint communication devices, said reconverted plurality of multiport packets using two or more ports associated with said multiport communication protocol.
