[DM-MUG] Q ref firewall communication port 3689: Apple TV not syncing with iTunes

[Victoria L. Herring]

I have checked the Apple site and discussions and talked just now to 
an Expert but can't find an answer and thought I would ask here in 
case someone has had the same issue.

I have an Apple TV which was running 2.0 and upgraded to 3+ - 
iTunes9.0.2, Snow Leopard, now.  Before I had ATV 2 and iTunes9+ and 
10.5.8...no problems at all using the ATV.

Upgraded ATV to 3+ and computer to SnowLeopard...although the ATV 
shows up in the Devices area of the iTunes, it can't connect to the 
library.

Network is fine.  ATV can see theatrical trailers and play music from 
internet.  I did a wipe of the ATV and reinstalled factory defaults 
and set it up again, upgraded the software to 3 and tried again.  It 
is seen in the iTunes but when I hit Sync it says the ATV is not 
responding "check that any firewall software running on this comptuer 
has been set to allow communication on port 3689."

I did not have the software firewall running.  I did have 
VirusBarrier X5 running [no problems using it and having ATV working 
before this] but did turn it off for a bit while I am troubleshooting.

I have aNetgear GS108 switch [not router, no ports to set up] and 
just talked to the cable company which says its modem/router doesn't 
have such selections.  It's a 'bare' broadband modem.

So, there's no place to set port 3689 that I can find.  None of the 
pieces of hardware has any problelm, network is fine.  Internet is 
fine.

But ATV won't sync with iTunes.
