firewall:iptables:ip-address:block:address
Block incoming traffic from specific IP addresses.
$ sudo iptables -A INPUT -s ${ip_address} -j DROP
try on your machine
This command adds a rule to the INPUT chain of iptables firewall. The rule drops (i.e., discards) any incoming traffic from the specified IP address (${ip_address}). The "-s" option specifies the source IP address and the "-j" option specifies the action to take if the rule matches, in this case, to drop the traffic. The "sudo" command is used to run the iptables command with root privileges.
