I recently purchased a hauppauge 2250 tv tuner card for my pc. I am running windows 7 64 bit. I have a netgear wndr3300 router a surfboard cable modem and avg free anti virus software. With the tv tuner came software to extend tv shows to an iPad within a home network and remotely from outside a home network. I have setup port forwarding and was able to get the tv extended to my iPad within my home network however when I run a test to see if I opened a port for outside the home network it says the port is closed. Does anyone know how to fix this problem? Thanks!
