*===========================================================================
* ipnet_nat_proxy_h225_msg
*===========================================================================
* Description: Track H.225 packets.
* This function handles the H.225/Q.931 call signalling packets. NAT calls
* this function after translating the address and port number in the IP and
* TCP headers, and when the source or destination port is the H.323 port
* registered to NAT during the H.323 ALG registration (the standard port for
* H.323 protocol is 1720). The H.225 call signalling protocol is used in H.323
* to establish connection between two end-points.
*
* This function must look at both an outbound as well as an inbound packet.
* H.323 connection can be attempted from local to global endpoint or vice
* versa.
*
* NOTE 1:
* The fields in the H.225 message are ASN.1 encoded. However, due to schedule,
* constraint, rather than employing an ASN.1 decoder, this function uses a simple
* strategy to look for the ip+port address in the H.225 payload by taking advantage
* of the fact that the port number always follows immediately after the ip address.
* Since the ALG can get the expected ip address from NAT, it can search byte by
* byte for this ip address to locate where it is in the H.225 payload..
*
* Local host (L) <---------------> NAT <----------------> Global host (G)
*
* The tuple of IP address and TCP/UDP port number is sometimes called transport
* address in some publications, and the same terminology will be used here.
*
* Case 1: Local (L) endpoint to global (G) endpoint connection
*
* L starts a TCP connection to G and the H.225 call signaling session starts.
* The establishment of this TCP connection is all handled by NAT, so by now,
* NAT should have the bind entry for this connection. During the H.225 session,
* L will embed its sourceCallSignalAddress (ip/port) and G's transport address
* in the H.225 payload to G. Thus, this function must parse for each H.225
* outbound packet, look for L's transport address, and substitute it with the
* translated address obtained from NAT.
*
* In addition, this function must also observe the H.225 inbound packets from G
* to look for the H.245 transport address (ip/port) in the connect message from
* G. The port number provided by G here will serve as the H.245 port number.
* L will use this port number to open the H.245 TCP connection with G. So upon
* obtaining the H.245 port number, this function must also register the H.245
* ALG agent to NAT .
*
* Case 2: Global (G) endpoint to local (L) endpoint connection
*
* G starts a TCP connection to L via the NAT's H.323 static entry and the H.225
* call signaling session starts. As in case 1, the establishment of this TCP
* connection is all handled by NAT, so by now, NAT should have the bind entry
* for this connection. During the H.225 session, G will embed its sourceCall-
* SignalAddress and L's global transport address in the H.225 payload. So, this
* function must examine all inbound H.225 packets and substitute L's global
* transport address with its real transport address.
*
* In addition, this function must also observe the H.225 outbound packets
* to look for L's H.245 transport address which is embedded in the connect
* message from L to G. The port number embedded in this message will serve as
* the H.245 port number.
*
* G will use this port number to open the H.245 TCP connection with L. So, this
* function must also register the H.245 ALG agent to NAT upon obtaining the
* H.245 port number. Furthermore, since the H.245 TCP connection will be
* started from G to L, this function must create a new TCP bind entry for the
* impending H.245 port connection.
*
* NOTE 2:
* TCP sequence adjustment is not required since it is a binary substitution of
* IP address and port number in the payload. However, the checksum in the TCP
* header must be adjusted when the TCP payload is modified.
*
* Parameters: appdata - pointer to application data.
* applen - pointer to length of application data.
* param - pointer to proxy parameters.
* Returns: 1 = Packet modified.
* 0 = Packet untouched.
* -1 = Drop packet.
