I have a Comcast router/modem that I am setting up port forwarding up to port to a device inside of the network but after a few hours this router will cut the forward off I was thinking its a timeout somewhere in the device .... Any suggestions?

Make sure the device you are forwarding the ports to does not have power management enabled on the nic.

The device I am porting to is a home automation device, I am thinking this device should not power down

When the "timeout" takes place have you noticed a problem with any devices accessing the internet? Also, if you go into troubleshooting and logs, look at the time that the forwarding stopped and see if theres an error related to this. After going through the manual for this router, i havent seen anything where you can adjust a "timeout" or anything related. There maybe a problem with your cable and the internet is disconnecting/reconnecting, way too common with cable.

I have the Comcast Router D3GNV connected directly to an Air Port and the air port is providing wireless access to the Insteon Centrail Controller.  Not sure if the air port is timing out or ??? The User prefers to use the air port for there wireless connections...

Im  not that familiar with home automation, but the device should have a log. I would start by investigating the Insteon Central Controller. The airport could possibly be the problem, try changing the channel for the wifi. Your best option is to test the wireless when the remote connection to the controller stops.
