Firewall macro compiler
fwmacro is a library for generating iptables/ip6tables rules and to generate input files for iptables-restore and ip6tables-restore.
The library comes with two scripts: fwmpp and fwmc
The fwmpp command processes the simplified rules to a set of iptables rules and fwmc compiles a set of iptables rules to a iptables-restore file.
Typical setup/usage will be:
- Create files with default chain sets in /etc/fwmacro/chains[4|6]/
- Create a file with simplified rules in /etc/fwmacro/fw.rules
- Compile these with: fwmpp /etc/fwmacro/fw.rules
- Build restore files with: fwmc
- Install iptables rules with: iptables-restore /etc/fwmacro/ipv4.rules
- Install ip6tables rules with: ip6tables-restore /etc/fwmacro/ipv6.rules
