I am trying to make my NAT type to open for Xbox Live and it always says to have one of the ports to be set to both UDP and TCP and i've looked all over the internet and i seen images of other peoples set up having the option to set it to both. But for some reason, my router does not give me the option to set it to both. It only allows me to set it to TCP or UDP and my question is why is that? How can I get the option to set it to "both".
