A Linux administrator is configuring network traffic forwarding. Despite having proper iptables rules, the traffic forwarding is not working. Which of the following commands will allow Linux to pass network traffic between different interfaces?
To enable IP forwarding, the kernel parameter net.ipv4.ip_forward must be set to 1. This is done by appending net.ipv4.ip_forward=1 to /etc/sysctl.conf and applying the changes using sysctl -p. This command ensures that the system can forward packets between different network interfaces.
