Methods and systems for tunneling data associated with a packet based
multimedia communication standard are provided. The method includes
intercepting a library call associated with the multimedia communication
standard in a modified TCP/IP stack and registering identification data
associated with the library call. A modified Transmission Control
Protocol/Internet Protocol (TCP/IP) header is appended over a
pre-existing header of a data packet related to the identification data.
The method also provides for transmitting the data packet having the
TCP/IP header through a firewall. The TCP/IP header includes a TCP SEQ
number and a TCP ACK number to provide a stateful connection.
