Title: router port ??? [resolved]
Post by: flip city on December 18, 2009, 09:48:24 pm
Hi everybody,

 Hoping that I can find out something quirky that's going on with my router. I did a port scan using zenmap with the router as the target. port 53, 80 and 50127 were open. I entered the router as the admin and proceeded to close that mysterious 50127 port. OK. restart and recheck the ports with a fresh port scan....Guess What ??

50127 was back open !!

How can I find what program is opening that port ?? :(

It may be the firmware on the router. but as long as you do not have that port forwarded to anything on a local box, this shouldnt be an issue at all

Thanks MOE-Inx,

 Would the firmware use a static port or dynamic as this "unknown" port keeps shifting ?

I think this is in the "dynamic range", an area that is supposed to be used by applications to randomly open ports as needed.
