The Switch Pro could function as a managed switch offering layer 2 and 3 capabilities, but it lacks native security tools like a firewall or IDS/IPS found in specialized appliances. If your camera setup isn’t required to connect online, this shouldn’t pose an issue.
You’re right about the risks of linking cameras directly to the internet via an L3 switch without a firewall. It can expose your network to threats. Using UDP over a UDP port like 1234 adds another layer, but it doesn’t inherently improve security—it just changes how traffic is handled. Always review firewall rules and consider more secure configurations.
I rechecked your query and my answer. It seemed you intended to ensure connectivity for online access. If you need internet functionality, adding a router or firewall is necessary. The UDM-Pro/SE works well within the Ubiquiti ecosystem, offering solid protection with its basic firewall capabilities. It’s more than consumer routers but lacks advanced options. You likely won’t face issues running cameras behind it. The console integration simplifies setup and operation.
Consider a budget-friendly firewall device instead of an UDP proxy. Since cameras and Wi-Fi APs can communicate through the switch, you might not need a dedicated UDP solution. WiFi 6 mesh access points also function as switches without requiring additional proxy software.
The UDM-Pro isn't inexpensive, but it offers good value considering its capabilities. You can create your own pfSense setup using recycled PC components (which are generally affordable) or purchase a dedicated pfSense appliance—pricing is comparable to the UDM-Pro. However, pfSense doesn’t support UniFi integration. My view is to choose the UDM-Pro for better compatibility with UniFi, simpler management, and remote access. The UniFi APs still require a UniFi OS Console appliance for AP management, which the UDM-Pro provides natively unless you opt for cloud hosting instead. If you don’t need these extra features or have alternatives that meet similar needs, then it makes sense to go with the UDM-Pro.
