The files found in this directory are for an alternative network configuration
and IP filtering system for kernel 2.4+ based on /bin/sh. This system is
designed for use with a routing daemon like zebra. This system also uses
iproute
Most of what you should really have to edit is found in network.conf
The files and their uses are as follows:
network.conf: general network, bridging, QoS and some ptables configuration
items. Comments in here contain the current documentation
on the configuration items, which can even handle pppd,
wanconfig, and ciped.
ipfilter.conf: The shell script sused to set up the iptables
filtering/masquerading etc.
if.conf Lower level functions for configuring interfaces.
qos.conf Functions to configure Quality of Service using /sbin/tc
You should be able to do most things by editing the settings in network.conf.
See below for more details on this reccomended editing policy.
You will have to configure the firewall using the iptables commands directly.
Don't forget to save the configurations using the
'netscript ipfilter|ip6filter save' commands! Unlike the last version,
the firewalling and filtering is no longer configured from network.conf.
This has been done as stateful filtering has helped obviate the need for
great complexity in the firewall scripts, and more flexibility is possible.
It is a good idea to get down and get dirty with iptables and learn it,
which you will appreciate if you are running this to build a network - you
should understand things fully, or else you will get things wrong.
