I port scanned my router from the WAN side and can see port 21 is accepting connections. When I connect with FTP, I don't get a prompt for username/password and the connection just times out after a while, so that's good. However, I would like for the router to never accept connections on port 21 to begin with. Does anyone know why port 21 is alive in this odd way and if there's any method to completely disable port 21?
