    I have a back to back DMZ setup using ISA 2004 firewalls. I am trying to
    access external NNTP server as firewall client.

    I have setup the firewall chaining between the downstream and upstream
    servers with authentication.

    1. I have created an access rule on the upstream server.
    The protocol is NNTP
    Source network is Downstream Server
    Destination network is Internet
    User is same as used to configure chaining

    2. I have created an access rule on the downstream server.
    The protocol is NNTP
    Source network is Internal Network
    Destination network is Internet
    User is specific user with adequate rights on the downstream box

    When trying to connect to a remote NNTP server from an internal workstation
    using outlook express as the appropriate user defined on the downstream
    server, the following happens.

    1. From internal workstation to downstream server, the connection
    established is firewall client.
    2. From downstream server to upstream server, the connection established is
    SecureNAT.

    Is it possible to force firewall client connection from downstream to
    upstream server?

    Thanks in advance
