Having UAG sp3 trunk listen on non-standard ports?

Hi everyone,

First off let me state I am not a UAG expert, this is my first time working with UAG.

I'm trying to setup UAG to allow incoming traffic from a cloud service to an internal application.  The cloud service is non-configurable and must reach into the internal server on a non-standard ports like 3333 for http and 3334 https(examples).  

I have read that UAG sp1 didn't support anything but listening on 80 and 443.  Has this officially changed in SP3 so I can create a trunk listening on a non-standard port, and have it supported via Microsoft?

thanks!

Brian
