Hi Mike, What primary and secondary connections does the application make? Those are the key parameters. If the server listens on TCP 3101, create create a Protocol Definition for inbound TCP 3101 and create a Server Publishing Rule from that definition. If there are secondary connections, or if the server actually makes primary connections of its own, then create Protocol Rules to support those.

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?
