    Help!!

    I have recently moved my network from a Qwest DSL setup to a Eschelon
    T1 setup.

    For the past two years we have been running ISA server as our firewall
    and exchange 2000 as our email server. The ISA server (obviously)
    receieves all inbound and outbound traffic and determines what to do
    with it.

    Presently I have 9 other physical locations that connect into my
    exchange server (using either outlook or outlook express) for email.

    Since the switch of internet service providers, My users have been able
    to recieve incoming emails and but cannot send email out to the outside
    world.

    In talking with my new provider I have been told that I need to setup
    port forwarding for port 25, on the ISA server. Unfortunately I am not
    as knowledgible about how to do this as I need to be and need some
    help.

    Also I am not sure this is actually the problem in the first place. In
    the past we have setup some of our remote locations with this same ISP
    and those locations had problems sending email out from our server as
    well.

    Can someone help me with this issue. Right now I have my remote staff
    using the Exchange webfront to send email, but this isn't the most
    ideal solution.

    FYI the error my remote users are seeing is a 550 error.
