Hi,
I am running CentOS Linux release 8.2.2004 (Core) on a remote server. I
am
running the below iptables command to allow SSH port 22 from a specific source IP 219.91.200.59
iptables -A INPUT -m tcp -p tcp -s 219.91.200.59 --dport 22 -j ACCEPT
service iptables save
The above iptables ruleset is not working and I am still able to connect from the internet to SSH port 22. I look forward to hearing from you and thanks in advance.

EL8 does not use iptables by default - it's been replaced with nftables.

Hi,
I have run the below command but I am still able to connect from the internet. Do I need to add any drop traffic policy using nft?
#nft add rule ip filter INPUT ip saddr 219.91.200.59/32 tcp dport 22 ct state new,established counter accept
Any help will be highly appreciable. Thanks in advance.
