Explicit Firewall exclusion list for ProjectWise Design Integration Server

Hi,

We are implementing increased security in our environment. I cannot find this information anywhere.

I need an up-to-date explicit firewall exclusion list for PW Design integration server, Bentley Web Services Gateway, and Connection Client (Not "give internet access to the server"). 

By 'Explicit' I mean every URL. IP range, and Port on the internet that all applications need to function. I would like the list broken down into "Required to function" and "Optional".

Thanks in advance,

Trent.
