Weird issue with Arc Loader/Synology and access to ports

Hello,
I'm at a serious loss right now and there are multiple unfortunate moving parts to this.
I currently have 3 separate Arc boxes that I am trying to replace with a single Proxmox host.

I've gotten thru all the normal nonsense of installing Arc via Proxmox Scripts menu and running into problems since this is an AMD machine.
The system is working but when I try to install anything from 3rd party sources in the package manager or add Onvif security cameras, it appears those ports are blocked.
There are some weird exceptions to this - I can add one pure RTSP camera and it comes thru, but any Onvif cameras (eg. port 8080 or other normal Onvif port) are blocked.
This happens on my other Intel machine I tested this on too, so it's the whole network.

The main moving part in this is that I recently switched from stable but way too basic TP-Link Decos to Ubiquiti. This system seems stable but exhibits many bizarre behaviors, including not giving devices IP addresses immediately, and one device randomly using a completely different subnet with no changes made to it at all. Their insistance on content filters and firewalls may be secure but this is a network for testing and servers, and I wouldn't be in the least bit surprised there is something buried deep in the Ubiquiti's poorly designed layered menu GUI.

Moving forward and assuming this is completely a Proxmox configuration issue since it is appearing on multiple hosts, the Proxmox VMs don't have firewall turned on in them, what is causing this?
