When I type
bitcoin-cli getpeerinfo in shell, conspicuous property of the result are
14.xx is my address and others are peer's address. I know that Bitcoin client can do port forwarding using UPnP query to my router. so, I checked my router whether the port number(48302, 44660) is opened or not but, no any port is currently open. This is very strange point. my peers should cannot communicate with me without port forwarding since I'm using router.
Can you give information technically?
Sorry for my English
