QTS blocks connections at IP layer 3. This might limit the network connections of apps that run on their own network segment within QTS, such as apps that use Container Station.
To fix these issues, go to “Network & Virtual Switch” > “Virtual Switch” and check which network segments are used by each virtual switch. Then add these network segments to your IP allow list.
For NAS models that do not support “Network & Virtual Switch”, go to “App Center” > “Container Station” > “Preferences” > “Network”, and then add the network segments shown here to your IP allow list. You will usually need to add 10.0.3.0/24 and 10.0.5.0/24.
