I have a Linksys WRT1900AC. I am trying to get a piece of hardware to reliably connect with other items on my network. I have been having difficulties. The technical people said to made sure that my router is not blocking ports 22, 443 and 8080. How do I determine if my router is blocking any of them. Is there a location that I can access in the router that might specifically allow me to list them as "do not restrict?".
