Which is the best open source Linux Firewall software?

Hi Guys,

If anyone have an idea about open source Linux firewall, kindly share me the name. The Firewall should have Parental control for all end user activity, like internet usage with URL accessed, restrict the websites, DNS, DHCP, Port Forwarding, system monitoring, in the internal network.

Thanks and Regards.
