I've created an open guest network on my router (N600 Wireless Dual Band Gigabit Router Model No. TL-WDR3600 v1, 3.14.3 Build 150518 Rel.72050n). Internally nmap gives me:
Nmap scan report for 192.168.0.1 Host is up (0.041s latency). Not shown: 992 closed ports PORT STATE SERVICE 21/tcp filtered ftp 22/tcp filtered ssh 80/tcp filtered http 139/tcp filtered netbios-ssn 445/tcp filtered microsoft-ds 1041/tcp filtered danf-ak2 1900/tcp open upnp 49152/tcp open unknown
I don't understand why any of the ports are listed. When I use nmap on my secure wifi network I see:
Nmap scan report for 192.168.0.1 Host is up (0.044s latency). Not shown: 996 closed ports PORT STATE SERVICE 22/tcp open ssh 80/tcp open http 1900/tcp open upnp 49152/tcp open unknown
Didn't even know my router had ssh capabilities... Why is FTP showing on the guest network? How to find out what 49152 is?
