I'm pretty new to the community. I have searched for opening ports with bt home hub extensively and came across this post many times. Obviously the information here is outdated. So I just wanted to let everyone know that there is a really easy way to open ports with your BT Home Hub.
I have used this method myself and so have some friends. I was specifically looking to open ports for call of duty and change my NAT Type. This is the method that has worked for me and countless others, and its really easy!
