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.
Best Regards,
Kaushal
