Posted on 2007-10-18

I want to set up a BlackBerry 4.1.4 system with the Router component in a DMZ.  I know I need TCP port 3101 open on the Internet facing firewall, but what port(s) do I need on the internal facing firewall so the Router can communicate with the main BlackBerry Enterprise Server system?

thank you

    Not sure.
    Isn't this specified in te Install docs ?

    possibly  even the same port ?

    For the internal firewall it is as follows:

    You need an out bounded connection over port 3101, initiated by the BES bi-directional, to the router in the DMZ.

    So the make the connection to the router in the DMZ (over port 3101) and the router make the connection to the SRP (over port 3101).

    The port 3101 is the default port, you may change it....
