To stop the IPFW firewall on FreeBSD, you can use the following command:
service ipfw stop
This will stop the IPFW firewall and prevent it from starting up again when the system is restarted.
Alternatively, you can use the pfctl command to disable the firewall. To do this, use the following command:
pfctl -d
This will disable the firewall and flush all rules.
Note that you will need to use sudo to execute these commands, as they require root privileges.
It's important to note that disabling the firewall can leave your system vulnerable to attacks from the internet. It is generally recommended to leave the firewall enabled and configure it to allow only the traffic that you want to allow. If you need to make changes to the firewall rules, it's better to do so by modifying the firewall configuration files rather than disabling the firewall entirely.
