Ports mentioned online seem to include TCP/80 , TCP/443, TCP/5222 , TCP/5223 and TCP/5228
I would suggest testing this on a single device and checking logs through ASDM.
Perhaps even taking a capture of the clients traffic at the firewall might help a bit.
Isnt this a mobile device application? I have not used it myself.
It is a mobile application that works on android, mac and symbian. the application port and address keeps changing with every user session. however, I will complete the tests and get back to you with the result.
Did Cisco ever get back to you on this? I am having the same issue with my ASA allowing the TCP/UDP traffic throught. I don't want to just open up high ports.
Agree with Jouni,
Due to the nature of this applications the best way to see this would be with a capture,
Let us know as soon as you have it
