While this won't fix your problem, it's a bit dangerous to connect directly to WAN and skip the router. You're exposing your external IP address DIRECTLY to your computer instead of a private network.
If I were to scan your ports, I bet I could find a running torrent server... Xplay or similar media server using default ports... a web server .... etc. Best to use a router, tbh. If I were to do it on a router, I'd probably find nothing unless you explicitly setup port forwarding.
