Hello, I have 2003SBS w/ISA sp1 and i am trying to add Blackberry Enterprise Server (BES). The BES software needs to initiate outbound bidirectional tcp/ip connections to an outside server listening port 3101, and the proxy must be transparent. I think that i need to create a internal proxy address that can be translated externally to the host on 3101. Any suggestions on how this can be accomplished? Thanks in advance, Mike
