    I have a host behind a router and a firewall, the firewall has been
    configured to accept connection from this host to a server. I can
    telnet to the server from the host but not ping!! How can layer 3 test
    fail and yet layer 7 pass with flying colors?

    Maybe the firewall drops ping packets. Mine does. :)

    Proabably because your firewall is blocking pings.

    Yes, it does block ICMP requests. My objective is to connect to the
    server like as if I am inside the firewall and use it normally. The
    firewall has all of its ports open, for test purposes, when I try to
    connect to it, it asks me for my credentials, I then supply my
    credentials which I have cross-checked many times and they are fine.

    This still does not solve the problem

    Come on: The ping requests *are* ICMP packets.
    Of course they do not work if ICMP is blocked.

    A few questions.

    1. What type of firewall are you using?

    2. How do you know that all ports are open?
    If Ping is your only problem.......
