I discovered the "Advanced Settings > System Log > Port Forwarding" page on my RT-N66U. I can see two opened ports that I have not explicitly created/authorized. I have FTP, Telnet, Samba all disabled. I have no USB drive connected to the router.
TCP 8443 (forwarded to the router itself)
UDP 50522 (forwarded to a Windows 7 PC on my LAN)
I found that TCP/8443 is:
SW Soft Plesk Control Panel, Apache Tomcat SSL, Promise WebPAM SSL, McAfee ePolicy Orchestrator (ePO)
but I don't recognize those services - why does the router need this?
More importantly, why has a dynamic port UDP/50522 been opened on a LAN PC? Is this something that UPnP enables?
I understand port forwarding and have manually forwarded the ports necessary to access what I need on my LAN from the WAN. I'd like to know if UPnP opened this port, why, and also what would happen if I disabled UPnP on my router? Is there anything I couldn't support by manually forwarding ports?
