This is a new installation of OmniFocus on the iTouch. The local firewall is off and Bonjour is obviously working as the iTouch detects the host database.

This issue is reported elsewhere but those users had restrictive Firewall settings on their Mac and fixed it by opening up the firewall. My Mac firewall is not denying this traffic. A colleague in the same office on the same WiFi network can sync without troubles (using OmniFocus Desktop v1.5) so I also doubt its firewall settings on an upstream router.

Any ideas what's up?
