regarding to usage way of UFW in NGINX
hello, I use ubuntu 14.04 version and I read article on
[https://www.digitalocean.com/community/tutorials/how-to-setup-a-firewall-with-ufw-on-an-ubuntu-and-debian-cloud-server](http://), got some curios thing that I would like to know usage of UFW
first question is I chaged basic port 22 to 2345 that I access /etc/ssh/sshd_config
after restart ufw, opened ssh port through Ufw allow ssh. but keep opened 22 port
do I have to open ssh port to ufw allow 2345 after block 22 port using by ufw deny 22?
and second question is i tried to access using 2345 port on sftp
actually it is possible to download, upload file on ftp through Root account. but after made my
account suddely showed up message ‘Deny permission and can not upload and download.
how can I get permission?
below is my last question.
google bot or cloudflare’s ip automatically block when enable ufw. should I each and every time open
by using ufw allow ip/port?
