How to make sure router isn't restricting three ports
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?".
Kindly elaborate on exactly what you are trying to achieve in your architecture so that we could help you out.
