Non-technical Overview

BBFW is the simple Linux firewall with a 1 to 1 feature match with iptables, ip6tables, and ipsets. As a bonus, the package also includes BBNET, BBFW's little networking brother. BBNET is the simple Linux networking script with 100% feature polarity with all versions of iproute2. Download now and also receive bbfw-log and bbnet-stats absolutely free. Don't miss out and download your copy today while supplies last.

Side affects may include consistent firewall rules accross your organization, server clusters with matching firewalls, and the ability to test your firewall rules on the CLI using the same syntax as your firewall configurations

Technical Overview

This package contains the Bindle Binaries firewall script for Linux systems. BBFW allows an administrator to create separate configuration files for global rules (i.e. oraganizational rules), cluster specific rules, application speciic rules, and server specific firewall rules. The configuration files containing the rules are loaded in a set order which allows each level or rules to build upon the previous rules.

Configurations

BBFW uses global configurations, application configurations, cluster configurations, and local system configurations. Each set of configurations may contain iptables, ipsets, pre hook scripts, and post hook scripts. The iptables and ipset files are piped into iptables-restore and ipset restore after unwrapping escaped new lines and stripping comments.

Files are processed in the following order:

  /etc/firewall.d/global.d/pre-hook   - centrally maintained pre-hook script
  /etc/firewall.d/apps.d/*/pre-hook   - app pre-hook script
  /etc/firewall.d/cluster.d/pre-hook  - cluster specific pre-hook script
  /etc/firewall.d/pre-hook            - host specific pre-hook script
  
  /etc/firewall.d/global.d/ipsets     - centrally maintained IP sets
  /etc/firewall.d/apps.d/*.ipsets     - app specific IP sets
  /etc/firewall.d/cluster.d/ipsets    - cluster specific IP sets
  /etc/firewall.d/ipsets              - host specific IP sets
  
  /etc/firewall.d/apps.d/*.rules4     - app specific IPv4 firewall rules
  /etc/firewall.d/apps.d/*.rules6     - app specific IPv6 firewall rules
  /etc/firewall.d/apps.d/*.rules      - app specific IPv4/IPv6 firewall rules
  
  /etc/firewall.d/rules4              - host specific IPv4 firewall rules
  /etc/firewall.d/rules6              - host specific IPv6 firewall rules
  /etc/firewall.d/rules               - host specific IPv4/IPv6 firewall rules
  
  /etc/firewall.d/cluster.d/rules4    - cluster specific IPv4 firewall rules
  /etc/firewall.d/cluster.d/rules6    - cluster specific IPv6 firewall rules
  /etc/firewall.d/cluster.d/rules     - cluster specific IPv4/IPv6 firewall rules
  
  /etc/firewall.d/global.d/rules4     - centrally maintained IPv4 rules
  /etc/firewall.d/global.d/rules6     - centrally maintained IPv6 rules
  /etc/firewall.d/global.d/rules      - centrally maintained IPv4/IPv6 rules
  
  /etc/firewall.d/global.d/post-hook  - centrally maintained post-hook script
  /etc/firewall.d/apps.d/*/post-hook  - app post-hook script
  /etc/firewall.d/cluster.d/post-hook - host specific post-hook script
  /etc/firewall.d/post-hook           - host specific post-hook script

Hook scripts are called as either start or stop as the first argument. These scripts can be used to synchronize configurations from a server, start/stop daemons, or generate dynamic rules.
