I had not seen that page but scanning through it the most likely
candidate is port 443 which I had seen elsewhere. However I see no
simple way of closing that port in DD-WRT. Closing it in iptables on
this computer wont stop iCloud to the Macs, etc. I tried blocking
several ip addresses I found Googling but that was not enough, perhaps
not a complete list?
It also mentions 5523, Apple Push Notification Services. Dropping that
at the router may do what you need.
