Hello, I have developed a Mac app that communicates with the iPad through Bonjour. One my customers, however, experiences problems with connecting both devices. It is difficult to remedy this through email. I was wondering if the Bonjour service could be disrupted by his firewall. He tells me that the Mac app is accepting incoming connections, but that both devices can't find one another on the network (same network). Do you have any suggestions or recommendations? How would you tackle such an issue (this is the first occurrence of this issue and I cannot replicate it myself). Thanks!
