Question about some settings in router

[jimdagys]

I have a router that someone set up. I was looking at the different pages inside the router ( I am clueless about understanding routers) because I was curious. One page ( see screenshot) had some entries (torch and utorrent). My question is: I never entered this information into the router, so how did these entries get into the router?

Likely UPNP (Universal Plug N Play), if enabled it allows your OS to automatically open ports on your router.

I'd also vote for it being UPnP. I know uTorrent has a setting to disable it, but then you'd probably need to manually add port forwarding to your router's configuration for uTorrent to work correctly.

By default uTorrent opens a port using a different (random) port number each time it runs. The setting's under "Connection" (at least for the older version of uTorrent I use).
