Iptables Firewall

Iptables can control all traffic to and from the internet, and all traffic to and from other computers on a network. It can be used to keep the computer secure.

To use Iptables, you must Install it.

Basic Firewall

To start a basic firewall each time Tiny Core is started, add

sudo /usr/local/sbin/basic-firewall

to /opt/bootlocal.sh.

Before connecting to the internet, turn the computer off and restart, so the firewall is running.

To save settings, you must Backup the first time you shut down Tiny Core after modifying bootlocal.sh.

This basic firewall is adequate for most home users.
