My domain https://www.pinbargain.com is hosted on lightsail received some suspicious IP addresses, therefore, I followed this document
https://docs.bitnami.com/aws/faq/configuration/block-suspicious-ip/
to block some suspicious IP address
I use this command to block the IP address:
iptables -A INPUT -s 1.2.3.4 -j DROP
Now the problem is I cannot remember the IP addresses I blocked. therefore, I want to find the IP address I blocked.
After that, I want to unlock some IP addresses.
How to do that?
