The Firewall Configuration Tool
This package configures your Linux box as a firewall. You can define your
firewall architecture
with/without perimeter and/ or internal networks. Click
here to get
an overview of the supported configurations.
Things you have to do to setup the Firewall:
-
Setup your Network
configuration.
-
Define the services which are available on your Firewall.
-
Configure
the services you want to use on your internal and perimeter networks.
-
Setup/add your Definition
of (new) services.
-
Describe the Screening
rules for the services from/to your internal and perimeter networks.
-
Generate the IP-Filtering Rules
to setup your specified services.
-
Define Trusted
external IP´s with the corresponding devices.
-
Setup some Aliases
(variables) you want to use within the configuration.
You have to process at minimum steps 1, 2, 6.
If you don´t have an internal/perimeter network, steps 3,
5 are obsolete.
Don´t forget to re-build the IP-Filtering rules (step 6),
after changing a definition in any mask
- except the Configure mask, this definition is evaluated at runtime
within your rules.
When you are finished, you should test
your setup and examine the created rules in the logfile.
You start the firewall whith the command ´firewall
[-v] start´.
