I am having an issue with port forwarding on my internet connection. I have a TalkTalk router that goes into a Google wifi. I have port forwarded my public IP to the Google wifi IP then forwarded from google to my PC for a MC server but the port is still showing closed. The setup is that from the talktalk hub a cable goes to a gigabit modem and then into TP Link extenders to my PC. Is there something im doing wrong?
