This allows for more flexible ipfw configuration files using `variables' to describe frequently used items in the file, like the local IP address(es), interface names etc. Both m4 and cpp are useful and supported; with m4 being a little more unusual to the common C programmer, things like automatic rule numbering can be achieved fairly easy. While i was at it, i've also untangled some of the ugly style inside main(), and fixed a bug or two (like not being able to use blank lines when running with -q). A typical call with preprocessor invocation looks like ipfw -p m4 -Dhostname=$(hostname) /etc/fwrules Someone should probably add support for this feature to /etc/rc.firewall. |
