FCT - Firewall Configuration Tool
This package configures your UNIX 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 can 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
for the specified services.
-
Test the created IP-filtering rules
for each service.
-
Define Trusted external IP´s
with the corresponding network 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 or 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.
When you are finished, you should test
your setup and examine the created rules in the logfile.
You start the firewall with the command ´firewall
[-v] start´.
