I'm new to ufw tool, I'm trying to block a specified host from requesting telnet while allowing other hosts on the network to do so.
When I use this command:
sudo ufw deny 23
The other host is unable to telnet to me. However, this denies everything that uses port 23 and all other hosts who attempt using telnet.
Therefore, I have tried the following:
sudo ufw deny from HOST port 23
sudo ufw deny to HOST port 23
I was hoping this will deny that host but it literally did nothing. The other host is still able to telnet as if the rules do not exist.
What am I doing wrong?

May I know why I'm being downvoted? Is the question not meeting some standard? Or just some guy who decided the question is too easy for him that it doesn't qualify to be asked? I said I'm new and I needed help. Thanks for discouraging people to ask for help. – Everyone – 2018-02-12T09:19:23.787
