Port Forwarding on Mac OSX

If your running vagrant and you're forwarding traffic to vagrant over 8080, but you really prefer to hit port 80, you can use Mac's pfctl function. 

Here's a couple of links that you might find helpful

I was reading this article http://salvatore.garbesi.com/vagrant-port-forwarding-on-mac/ and it suggested adding a vagrant plugin, but it's a ruby gem. Hard to imagine, but the gem failed to install.

You can still implement port forwarding. Create a pfctl.conf file in your vagrant folder:

echo "rdr pass on lo0 inet proto tcp from any to 127.0.0.1 port 80 -> 127.0.0.1 port 8080
rdr pass on lo0 inet proto tcp from any to 127.0.0.1 port 443 -> 127.0.0.1 port 8443" > pfctl.conf

To run this, you first need to enable pfctl

pfctl -e -f pfctl.conf

Once you enable the firewall rules, you can hit your vagrant box by going against localhost. 

To disable pfctl: 

pfctl -d
