> Check router setup
When I logged into my Netgear router, I found that port forwarding and universal plug and play (UPnP) were on, but didn’t show any devices. Should I turn them off?
Port forwarding redirects incoming connections sent from outside your local network to one IP address and port number, to a different address and port on the local network. This provides external access to services like a local web or FTP server, and requires careful configuration.
