[missing-sync-pocketpc-talk] Firewall issues

[andy_park at nospammail.net]

Does Missing Sync always use the same port when a connection is made 
between the Mac and PocketPC? Is it dependent on what type of media is 
used(USB v. Bluetooth)? Ideally, I'd like to keep my firewall up and 
running at all times and be able to get away with a custom rule. Port 
990 has been mentioned at one point on the list - would setting up a 
Missing Sync compatible firewall as simple as opening up port 990 from 
192.168.206.206?

Your insights please.
