    Hi,

    I've published a rule in TMG from Exchange to Internet with port 25. But, the emails are being denied at TMG as shown from the log below.



    my TMG is using one arm network topology (i.e., only one NIC)

    Further, the log shows the source is internal, the destination is internal.

    How do I port forward port 25 from TMG (internal) to Exchange: 10.0.0.111

     
    Useful info:

    TMG: 10.0.0.1
    Router: 10.0.0.21
    Exchange: 10.0.0.111
    Internal DNS: 10.0.0.100
