Mac OS X Firewall Tricks to Forward Ports 3001, 3002 to 80 and 443 respectively

• OSX 10.10 Yosemite

  This is needed because virtualbox cannot bind to privileged ports. SH Tunnel (easy & safe)

  sudo ssh  -gNL 443:localhost:8443 YOUR-USERNAME@localhost
  

  Packet Filter (might conflict with local firewall rules)

  echo "rdr on en0 inet proto tcp from any to en0 port https -> lo0 port 8443" |sudo pfctl -f -
  

• OSX 10.{9,8,7}

  ipfw add 1 fwd 127.0.0.1,3001 tcp from any to me dst-port 80
  ipfw add 1 fwd 127.0.0.1,3002 tcp from any to me dst-port 443 
  

  if you would like to run without invoking the caching / layer (also disabling forced ssl + security headers)

  ipfw flush
  ipfw add fwd 127.0.0.1,3000 tcp from any to me dst-port 80
