Port Forwarding in Mavericks

Since Mavericks stopped using the deprecated ipfw (as of Mountain Lion), we'll be using pf to allow port forwarding.

1. anchor file

Create an anchor file under /etc/pf.anchors/<anchor file> with your redirection rule like:

View my-bootstrap.bat
@echo off
rem 03.02.2012, setup of directories may vary
mkdir bootstrap\img
mkdir bootstrap\css
mkdir bootstrap\js
copy img\* bootstrap\img
node.exe f:\nodejs\node_modules\less\bin\lessc.js less\bootstrap.less > bootstrap\css\bootstrap.css
node.exe f:\nodejs\node_modules\less\bin\lessc.js -x less\bootstrap.less > bootstrap\css\bootstrap.min.css
