The DHCP IP Firewall script is a Linux 2.4.x and iptables compatible project designed to create a firewall script. This script manages firewall operations, specifically DHCP and IP management tasks. It is intended to enhance network security and stability.
The DHCP IP Firewall script project is a powerful Linux 2.4.x and iptables script that is designed to provide advanced firewall capabilities to Linux users. With a range of configuration options, this script allows users to quickly and easily set up their local area network and configure their internet connection.
The script includes a range of configuration options that can be used to quicken the set up process. These include options for configuring your LAN's IP range and localhost IP. The script also allows users to define the broadcast address and interface for their LAN.
In addition to these local area network configuration options, the script includes configuration options for the localhost and internet connections. Users can specify the local IP address and interface for the localhost, and can also set up the internet connection with the appropriate interface.
For users who need DHCP over the internet, the script provides a DHCP configuration option. Users can set the DHCP variable to "Yes" and specify the IP address for the DHCP server in the DHCP_SERVER variable. For users who do not require DHCP over the internet, the DHCP variable can be set to "No".
The script also includes configuration options for PPPoE. Users can set the PPPOE_PMTU variable to "Yes" to fix any issues they may have with their PPPoE connection, such as large mails not getting through while small mail get through properly etc. The script sets a rule in the PREROUTING chain of the mangle table which will clamp (resize) all routed packets to PMTU (Path Maximum Transmit Unit).
Finally, the script includes IPTABLES configuration options that allow users to configure their iptables searchpath and other options. The IPTABLES variable can be set to the appropriate path for the iptables package.
Overall, the DHCP IP Firewall script project is a powerful and flexible script that provides advanced firewall capabilities to Linux users. With its range of configuration options and ease of use, it is an essential tool for anyone looking to secure their network and ensure the safety of their devices and data.
