Hi there,
i was searching around the forum and the web for solving an issue with 2 iPhones (3GS and 4) and Apples Push Notifications. They didnt work correctly on Wi-Fi behind an ASG.
I solved the Problem by opening the TCP Port 5223 FROM the Decive to the External Network (WAN) - no i have a Packet Filter Rule for the "iPhone-Group".
so the Packet Filter for one device (it should use a static IP - or open this port from all LAN devices): Device-IP->TCP(5223)->Any - Allow
The Information about the used Port i got from here -> About Apple Push Notification Service
This Thread may help other people which have the same issue.
Greets,
Martin
