The use of IpTable Frontend is easy. I'll try to guide your first steps.
Get and install .Net framwork. I've tested it under Windows XP,
using native Framemwork 2.0, and also under Linux, using Mono
pre-installed into Opensuse 10.2 Distro.
Obtain the "game" here. Ignore sources and double click on the exe
file ( IpTableFronteEnd.exe ) . In doubt get fire !!
Once started you can : create a blank configuration, load an existing
one ( I suggest you to make your own template for re-using it ), start
the wizard. ( The last one is till under construction ).
Proceed configuring general settings.
I mean the various parameters which define your specific layout and
The order of the various tabs will guide you adding ever more detail.
The devices may be automatically detected using wizard
Make your rules !
The rule are divided into General, Specific and Special.
The Generic rules are applied before the specific rules could act.
It's the best place for placing super user access and exception.
The Specific rules organize the traffic into chains ( as Iptables do ) .
Each chain ( you can add your own ) has a set of catching rules,
which defines the packets kind that belong to the chain, and a list
of matching rules that, instead, gives instructions about the chain
For example you can re-direct all SMTP traffic to the SMTP chain
and then allow only your mailserver to get access outside.
The packets which enters into the Chain and are Dropped or
Rejected will be logged ( once the firewall will be loaded ) into
Try using wizard button. ( Load hosts before )
The Special rules lets you to specifiy NAT and/or Port-Mapping.
Keep in mind that all tables are available, but that default value
presented are the best one.
However for a full parameters understanding see IpTable site
( you'll find a lot of documentation ) - www.netfilter.org
Click the Build button and your rules will be magically written into
your destination script file.
The output file is self running and you can place it everywhere and
run it at system start-up.
This file is organized in the way that every value is a variable, so you
can continue managing it using IpTable Frontend or by your end with
Vi, or other text file editor.
