==================

 * ifup(8), ifdown(8), and interfaces(5)

The ifup and ifdown commands configure network interfaces as specified
in the /etc/network/interfaces configuration file.

ifup -a is called from /etc/init.d/networking as part of the bootup
process, or for specific interfaces by the hotplug subsystem.

 * /etc/network/options

This file is deprecated, and if present should be replaced by values
in /etc/sysctl.conf or equivalent custom scripts.
The relevant sysctl values are:

ip_forward=yes:	  net.ipv4.ip_forward = 1 
spoofprotect=yes: net.ipv4.conf.default.rp_filter = 1
                  net.ipv4.conf.all.rp_filter = 1
syncookies=yes:   net.ipv4.tcp_syncookies = 1
