I will take a look at the links later - thanks.
As for a backup config.xml - this was a clean HA install, so the config should also be clean, however I have resolved the proxying issue, the ports being blocked I believe is more firewall related since I cannot connect to those IPs internally either, which do not go through the proxy, but will go to PfSense as a gateway.
I appreciate the help, but I think for the most part I have moved on from this for now, my only real issue is one I can bear with for now since I have used different IPs.
