How do you close open ports?
I have been running port scans using nmaps and other software. It that shows there are 9 open ports. If I use an online check to see if these ports are open they are reported as closed. Should ...
PORT STATE SERVICE
21/tcp filtered ftp
53/tcp open domain
80/tcp open http
443/tcp open https
631/tcp open ipp
3333/tcp open dec-notes
5555/tcp open freeciv
20005/tcp open btx
49152/tcp open unkn
I get this report if i run nmaps locally using my local ip number for my router (192.168.x.x)
All ports shown as 'stealth, when using shileds up.
Thank you

If 53 is not open, no device will be able to access the internet in any practical way. Port 80 is used to administer the Orbi.
Since these are all on the LAN side, I do not see these as an issue (although I will continue to look at them).
MUCH more interested in what Gibson says about from the WAN side (where the bad guys are).
Thank you
53 port is open on the LAN side is that OK do you think?
I am not aware of the Gibson comment about the WAN side,

When I use the Gibson security (free) port scanner: https://www.grc.com/x/ne.dll?bh0bkyd2 and select "All Service Ports", my Orbi does not respond on port 53.
How are you getting at the "public" side of the Orbi?
Sorry thank you, i used that link, did not realiise it was gibson.
yes port 53 is closed on thhe WAN Side.
Thank you for all yor help and advice.
