What line to enter for "Remove the rule allowing you to connect from 94.229.*.*?

Question

SSH

I was told to enter:

iptables -D INPUT -s 94.229.0.0/16 -p tcp -m tcp --dport 21 -j ACCEPT

But it comes out

Bad rule (does a matching rule exist in that chain?)

. What's wrong??

Answer 1

And what does the rule look like in the output of iptables --list-rules ?
Find it there and replace -A with -D.
