GMS Linux

I am running GMS Linux and it works fine, I have had to set the server to listen on a different port as we also have GW Webaccess running on Apache.

Everything is fine with the exception of package downloads which fail, it seems that they are trying to pull from the server on the default port and obviously not finding anything. I see this when doing download to the PC, and trying the install directly from the client device fails.

Where can I specify the port for the download URL?
