Help with Essbase Ports

Question

Does anyone knows if you can set a specific port for each APP.
Before we had Essbase 5.0.2 and we have upgraded to Essbase 9.3.1.
Several users connect to different DB from the internet. We had configured 3 ports for access in the firewall, 33005, 33010 and 33015.
Each port was used to access a different DB,
DB A -> 33005
DB B -> 33010
DB C -> 33015
The problem that we have now is that every DB we start uses 2 ports, so when we start the 3 DB, the first one uses 33005 and 33010, the second uses 33015 and 33020 so the third can not be accessed through the internet.
I have try with PORTINC, but the main problem is that the open ports ends with 5, so I can not make the 3 DB visible.
So what I would like to know if you can assign an specific port to a specific DB.
I want to avoid any modification to the firewall, because that would mean I have to make a request to another area and that takes time.
Thanks in advance.

I don't believe the ports can be isolated to specific databases (unless the databases are isolated to individual servers, that is -- and you don't want that).
In version 5, the ports did use increments of 5. This is no longer the case though, since version 7, the default is now 1 (which makes a lot more sense now). You should open up a wide range for "other" reasons (mostly to avoid the issue with "unable to send/unable to receive" due to all available ports being in use). You should look at the technical reference for the PORTINC, SERVERPORTBEGIN, and SERVERPORTEND entries and match the firewall to the settings applied to the server.
Basically, the need to keep the number of ports to a minimum should be evaluated against the need to provide sufficient access. If this is a firewall issue that IT is restricting access to, you should consider VPN access security as an alternative to public exposure to the essbase server.
