What firewall ports are required for Edge Transport server Anti-Spam (and other) updates?

The following article explains which ports need to be opened for the Edge subscription.

But I can't find anything that says if I need to open 80/443 for the Edge Transport server to receive the Anti-Spam (content filter etc) updates. Does anyone know how the Edge server receives its updates? Is it directly from the Edge Subscription (therefore no ports required beyond the above article) or does it need port 80/443 to get the updates from MS?
