Allow incoming traffic from specific network interface.
$ sudo iptables -A INPUT -i ${interface_name} -j ACCEPT
try on your machine

This command uses the iptables firewall tool to configure the system's firewall rules. Specifically, it adds a new rule to the INPUT chain, which applies to incoming traffic destined for the system.

The "-i" option specifies the interface name for the traffic to be accepted on. "${interface_name}" should be replaced with the actual interface name, such as "eth0" or "enp0s3".

The "-j" option specifies the action to take if the traffic matches the rule. In this case, it will ACCEPT the traffic and allow it through the firewall.

The "sudo" command is used to run this command with root privileges, as iptables configuration requires administrative access.
