Hi I recently signed up with Xfinity and am using the Xfi web interface to configure port forwarding.
I have two devices for which I need to set up port forwarding; each has a non-configurable port that they listen on, and since they are the same device, the port is the same in both cases. Before using Xfinity, this wasn't a problem, because I simply chose 2 different external ports.
The Xfinity port forwarding interface seems to assume that the source and destination port are the same. Because of that, I can only forward the port for one of the devices. Is there some sort of "advanced" section where I choose different external and internal ports instead of assuming they will always be the same? I've never encountered this situation before - in all other firewalls and modems I've always been able to set the internal and external ports separately, so I'm assuming I'm just missing something.
