Can't get apple tv to communicate with iTunes or any of my other apple devices.

Question

I have an Apple TV, iPad, and a couple of iPhones and an iTunes account with the Home Sharing feature tuned "on".  When I first connected my Apple TV to my network everything worked correctly, I could use the Remote application from each of my devices to control iTunes, I could mirror from my devices to the Apple TV using Airplay and had no problems with Home Sharing.  However, after about a week of everything working perfectly it all stop working.  Now I can't get any of my devices to communicate across my network and none of my devices can utilize Airplay, Remote app, or access iTunes via my wireless network.  I spoke with an Apple customer service rep who told me that the router will monitor traffic from certiain ports and block them if it thinks that the traffic is coming from a perceived security threat.  He suggested that I set up port forwarding in my router for the most commonly used ports by apple devices and software.  So I followed his suggestion and made the following port forwarding settings:
Service Name
External Start Port
External End Port
Internal Start Port
Internal End Port
Internal IP address

Apple Tv - iTunes - Bonjour

By the way, my router is a Netgear WNDR3400.  After making the port forwarding setting I still can't get any of my devices to work properly.  My Apple TV will communicate with my desktop computer if I connect it to the router via a hard wired connection but it will not work via a wireless connection. Anytime I try to access the Remote application on any of my devices I get the message that says "Turn on Home Sharing in iTunes on your computer or on Apple TV. - I have checked multiple times to see that I have Home Sharing turned on and I can assure you that it is.
I am running the most up to date software versions on all of my Apple devices, iTunes, and my Netgear router. 
Any help with this matter is greatly appreciated!  Thanks in advance.

One thing I forgot to mention is that I am running Windows 7 and I have already gone into the firewall security setting and told it to allow all of the apple programs like bonjour and iTunes through.
