The firewall should not be getting in the way here, these connections are all internal. If by mirror mode you mean you are using AirPlay, then I would look at your wireless environment. Run a speed test to http://speedtest.comcast.net from a wired system, then a wireless system (like a laptop, etc). Are the results very different? If so you may have a wireless issue. Try changing the wireless channel on the gateway, reposition the gateway to a more central location, away from the wall, higher up, etc. Do you have cheap cordless phones? These are a very common source of interference, as are other wireless devices.
If the wireless environment seems fine, then you might want to check the position of the Apple TV, make sure it's not blocked by anything metal, etc. If at all possible, connect it with ethernet to the gateway.
Check your iTunes server, make sure it the system is not overloaded, running out of disk space, no corruption in the iTunes Library, latest version of iTunes, etc. Check the system's network connection for any signs of a problem, like slowness, bad cable, etc.

There are NO ports required to be open for the Apple TV to function, and since you're talking about local usage, you are NOT traversing your Comcast connecton when you use AirPlay and straming content from iTunes to your Apple TV.
If the Apple TV can access Netflix and YouTube with no problems, and it's ONLY iTunes or AirPlay streaming tht is an issue, then you need to look at the device streaming the content, or your iTunes setup. Make sure both the Apple TV and iTunes server are using the same Apple ID and that each device you are using is allowed to access that account (see your iTunes Store account details for the device count, limited to 5). Make sure the iTunes server is not generating any errors.
If still having a problem, list the exact setup and exactly what you are doing and how it doesn't work, any errors, etc. Be very specifc about hardware and software used, versions, config settings, etc.

You have a firewall on the laptop? If so, disable it and try again. If the laptop is set to go to sleep or hibernate after some time of inactivity, disable this and test again. If things still go south, reset the gateway to facotry defaults and try again. If still no joy, I would replacing the Apple TV. If that doesn't help, then replace the gateway with a good cable modem (or have it put in bridge mode by the folks at 800-363-2416) and get a decent high performance wireless router. Other minor possibilities include bad power connections to the Apple TV, wireless interference, etc.
I have a very similar setup, Apple TV (2nd gen), MacBook Pro, iPad (v1 not v2) and a Win7 desktop. iTunes runs on both the MacBook and the desktop, but my main music, movie, TV show, and audiobook library is on the desktop and the Apple TV is the main consumer of this content, including the occasional web video from the iPad. It's connected to a 47" flatscreen and Denon reciever in the bedroom. Works flawlessly using an Apple Time Capsule for wireless connections.

Hey Jpurvis - I'm having the same issues, with what I assume is a similar set up: TG 852, Imac connected via wifi, ipad, & apple TV... seems like the wifi connection is just cutting out on one or more of my devices at any given time (and obviously disrupting communication between the devices)
Just curious to see if you found a fix? I keep reading about bridging the modem and buying my own router and I think I'm close to being there... Just wanted to see if this fixed your issue?
