Turtle Firewall is a Linux 2.4.x and iptables-based firewall configuration project.
One of the key advantages of Turtle Firewall is the ease of editing the XML file or using the user-friendly web interface Webmin to make the necessary adjustments. This software is open source and written in Perl language, released under GPL version 2.0 by Andrea Frigido (Frisoft).
Turtle Firewall boasts of incredible features such as Zones, Networks, Hosts, and Groups definitions. With its filter rules definition based on services, users can create new service definitions, implement NAT, and Masquerading for better security.
However, creating your Linux firewall with Turtle Firewall requires some prerequisites: you need a Perl Interpreter, expat library (normally included in all distros), a Perl library for expat (XML::Parser), iptable command in PATH (with iptables >= 1.2.11). Also, Netfilter kernel modules must be installed or compiled into the kernel (ip_tables, ip_conntrack, etc.). Lastly, forward is enabled "Act as router"=yes in Hardware->Network->Routing webmin form.
In the latest version of Turtle Firewall, several new service definitions have been added, such as igmp (Internet Group Management Protocol), BPALogin (BPALogin), and openvpn (OpenVPN protocolo at www.openvpn.net). Bugs have been fixed in this incredible version of Turtle Firewall.
Overall, Turtle Firewall is an impressive and convenient tool for anyone who wants to create a secure Linux firewall. Get started with Turtle Firewall today and be impressed with its exceptional performance!
