Q: using imessage on mac and iphone both behind the same firewall
Hey guys.
I know that some people have had issues with iMessage useage behind a firewall, and I am having a related problem.
What I have noticed, is that if my iPhone 4 gets an imessage, it comes in over WiFi, and I will often respond to that message from the phone.
If I then get another message, and decide to reply to it on my MacBook, the reply will not send, and has a red exclamation mark next to the message.
If I click on it and press retry, the message sends fine, and subsequent messages are also fine.
If I then go back onto my phone, reply to a message, and swap back, I get the same issue again.
I can only assume that this has something to do with UPnP on my router, opening the port only for one device at a time?
Anyone else facing a similar issue, or able to suggest a possible solution?
Cheers
