I seem to be having an issue with the Network push element of GMS.

I have enabled the 'Enable Push' and disabled 'ReadySync' on the Admin
Console. I am using Network push only.

I have ports >1023 TCP/UDP open from my GMS Server to www (I believe
this is what GMS uses for push?) and port 3102 open inbound to my GMS
server for Readysync initiated connections.

All user initiated 'pull' connectivity functions, but the push element
does not work at all. The 'Sync Devices' are all listing their last
connect time, but show no network push times.

Could someone clarify the absolute requirement for ports for network
push to function.
