Port redirects and the turnkey app

Hi, 

I am always struggling wth these Apache settings, I downloaded the PHPCake iso's and they work nicely out of the box. 

My issue is I have 2 VM's one Dev and one QA : 

  Dev serves  port 80 and 443 via a port forwarding from my cable modem/router 

  QA I am trying to setup to respond ot 8184 and 8143 but I am unable to conenct to them 
  either directly 192.168.0.123:8184 or via my public ip address over the web.

 How do I configure the QA VM using webmin to have it serve those ports?
