So I'm pretty new to the vulnerability scanning thing. I'm running Kali Linux 2.0 on my LAN, and currently I'm running Zenmap to find open ports/services/etc...
I'm running it from behind my router outside, and back into my router (so it acts like the scan is coming from the Internet, not inside my LAN). As in... I'm using my public-facing router IP, not my private LAN router IP.
I noticed that port 23 (Telnet) is open, and it is even open when I ran my scan from the inside of the LAN. The problem is that I blocked port 23 from all traffic through my router, it shouldn't be open, but it reports that it is.
(1) How can I shut it off if the router is already blocking it? (Using a Netgear WNR1000)
(2) If it is a program from my LAN (or worse, an attacker from the outside), how do I find out which IP address it is coming from and shut it down?
* Also, any other tips/tricks for Kali Linux would be greatly appreciated !!
