By creating interface configuration, ip address, and gateway configuration will remain when machine reboot.  In Debian, this configuration can be writen in configuration file name "interfaces" in directory "/etc/network/".  The configuration file will have like this:

Iptables provides packet filtering, network address translation (NAT) and other packet mangling.

This post will show example of configuring firewall filter to protect routing engine in Juniper.  In Junos, to protect router itself (local routing engine) against attack, like DDoS attack, and TCP Sync attack, or unauthorized access, can be created using firewall filter then apply filter in loopback interface. This post will describe examples for protecting local routing engine against unauthorized access, also icmp, and tcp floods.

By creating new folder, and rename it to GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}, you have all you need for configuring your Windows 7.
