![]() ![]() Nevertheless, it can be used when they are the same machine as well. In the end, it issues command write mem to store new configuration in memory and logs out.īuilt-in policy installer has been designed to work with dedicated firewall machine, that is, when computer where you run Firewall Builder GUI and actual firewall are different machines. It inspects router’s replies looking for errors and stops if it detects one. In case of Cisco routers or ASA appliance (PIX), it logs in, switched to enable and then configuration mode and executes configuration commands one by one in a manner similar to expect scripts. Generated configuration files to the firewall machine and then uses ssh to log in and run the script. In case of Linux and BSD based firewalls it uses scp to copy Installer works differently depending on the targert platform. ![]() Full directory path to ssh client program can be configured in the Preferences dialog (accessible via Edit/Preferences menu), however if you are on Linux, *BSD or Mac and use standard ssh client that is available via your PATH environment variable, you do not need to change default value there. On Linux, BSD and Mac OS X it uses standard ssh client ssh and secure shell file copy program scp that come with the system on Windows it uses plink.exe and pscp.exe. The program does not include ssh code, it uses external ssh client. Installer needs to be able to copy generated firewall script to the firewall and then run it there. ![]() On Linux, *BSD and Mac OS X it uses standard ssh client that comes with the system on Windows it uses putty. Installer works on all OS where Firewall Builder is available: Linux, FreeBSD, Windows and Mac OS X. Starting with version 2.0, Firewall Builder comes with built-in installer that uses SSH to communicate with the firewall. This function is performed by the component we call “Policy Installer” which is part of the Firewall Builder GUI. Firewall Builder was introduced on this site earlier with articles Getting Started With Firewall Builder, more information on Firewall Builder, pre-built binary packages and source code, documentation and Firewall Builder Cookbook can be found on the project web site at Watch Project Blog for announcements and articles on all aspects of using Firewall Builder.Īfter firewall configuration has been generated by one of the policy compilers and saved in a file on disk in the format required by the target firewall, it needs to be transferred to the firewall machine and activated. This article continues the series of articles on Fireall Builder, a graphical firewall configuration and management tool that supports many Open Source firewall platforms as well as Cisco IOS access lists and Cisco ASA (PIX).
