    If your frewall drops the connection thru a TCP RST, change it so that
    it silently drops the packets. This will make the linux box hang waiting
    for a timeout.
    
    Then execute:
    
    	netstat -tanp | grep <port>
    
    on the linux box, where <port> is the source port you see in the Source:
    line on your firewall logs.
