How to turn off all default open ports?
There has below ports are scaned and remain opened, even I didn't activate those service on router or intrfanet. How to turn off those ports?
21/tcp filtered ftp 53/tcp open domain dnsmasq 2.39 ...
You can't turn OFF ports. Those are all automatic and used by something on your network/PC. Disabling some of those ports will cause problems anyways.
May I know why I cannot turn off ports?
I didn't enable any FTP, DNS, HTTP, and else service on the RBR50 or any devices on the intranet, nor port mapping on RBR50, since no services on intranet is required. But network scanner detect there has opend or filtered ports on the internet.
Does this suggest RBR50 has enabled those service without my authority? Why I cannot turn off those services to close those listening daemon?Please note that I wasn't scanning RBR50's private IP on intranet, but its public IP on internet.
