Buster21, the 9 port is not a blocked port so it can be used. It sounds like you want to access port forwarding. Here's more info: https://www.xfinity.com/support/internet/port-forwarding-xfinity-wireless-gateway/

BruceW, Ah, I see now. Thanks for the save!
Buster21, coax line amplifiers are installed by a tech and we use our own amps for that. I'm not sure what type of amplifiers techs use specifically, but we can send a tech to evaluate. Are you experiencing service/signal issues?
no I am not having a signal problem. I have a Control 4 system. I have A 5 port and it only allows for 3 tvs so if I want to run additional tvs thru the control4 I would need to go to the 9 port or else I would have to spilt the signal of before the 5 port to the other connections and i am afraid that would cause signal problems.
