    Hi,
    
    Lets suppose that I can execute a program on an inside
    host on a network protected by a firewall. There is no
    way in. But there is a way out to www browsing on port
    80.
    
    So the client could connect to any Internet address on
    port 80. What program should it execute to provide me
    with a shell? Of course I'm in Internet with a
    listener. What listener?
    
    The firewall is a real statefull firewall so no TCP
    ACK or ICMP encapsulations. 
    
    Have a nice weekend too.
    
    Ilici R
